BAZIC Products BAZIC Letter Stencil Sets, Sizes 8 10 20 30 mm, Letters Number Mathematics Sign, Clear Plastic Stencils, 1-Pack

What you get in the set

The Bazic stencil set packs a lot of utility into a small, classroom-friendly package. You get four sizes of the same character set—roughly 8 mm, 10 mm, 20 mm, and 30 mm cap height—covering uppercase and lowercase letters, digits 0–9, and a handful of basic math symbols. The templates are cut from clear, brightly colored PET plastic, which makes it easy to see your work surface while lining up letters and to spot the stencils in a busy classroom bin or a craft drawer.

The typeface is a clean, generic sans serif that lends itself to school projects, bullet journaling, labeling, and signage where clarity beats flourish. The variety in sizes is the hook here: the 8 and 10 mm sheets are ideal for notebooks and labels, while the 20 and 30 mm sizes handle posters, lockers, cubbies, and fabric projects.

Build quality and design

PET is a pragmatic choice. These sheets have a little flex but don’t feel flimsy. Edges are cleanly cut with no burrs or sharp spots, and the plastic is genuinely clear enough to see guideline pencil marks underneath. I appreciate that the plastic is thick enough to avoid buckling when you’re tracing with a firm hand, yet thin enough to keep the stencil edges close to the surface for reduced bleed.

The color coding is more than decorative; it makes quick work of grabbing the right size from a pile. I do wish the sizes were printed on the sheets for instant identification—after a few uses you’ll remember which color corresponds to which size, but labeled measurements would be a nice quality-of-life touch.

As for the character set, you’ve got what most elementary and craft tasks demand. The math and symbol selection covers basic operations and punctuation, but it’s not exhaustive. If you’re looking for Greek letters, arrows, or specialty punctuation, you’ll need to supplement.

In use: pens, markers, paint, and fabric

I tested the set with a range of media on paper, cardstock, painted wood, and a cotton tote.

• Dry media: Standard pencils and 0.5 mm mechanical leads work well across all sizes. The smaller 8 and 10 mm letters have some narrow apertures—think A, E, M, W—where anything broader than a 0.5 mm point becomes fussy. If your go-to is a chunky wooden pencil, expect to do some careful angle work on the tiniest characters.
• Fineliners and markers: 0.3–0.5 mm technical pens are perfect for the small sizes. An ultra-fine permanent marker fits the 10 mm set with a light touch. Chisel tips and classic bullet-tip markers are better suited to the 20 and 30 mm sheets; they’re simply too broad for the small stencils.
• Paint: With acrylics, I got clean results on cardstock and wood by using a stencil brush and a dabbing or pouncing motion. Brushing across the openings invites bleed under the edge, especially on the larger letters. Painters’ tape helps secure the sheet, and a light coat is your friend.
• Fabric: For labels and fun one-offs on cotton, fabric markers through the 20 and 30 mm sets worked well. I got best results by sliding a piece of cardboard beneath the fabric to firm up the surface and taping the stencil in place to prevent shift.

The clear PET, combined with the bright color tint, does a nice job helping you see alignment marks and baseline guidelines. There are no built-in registration marks, so plan to draw your own pencil baseline if you need perfectly straight lines or consistent vertical centering.

Precision and legibility

For a budget-friendly set, the cuts are impressively consistent. Strokes are even, letterforms are balanced, and the internal counters don’t collapse or warp with regular use. The resulting text has a neat, uniform look that lands somewhere between schoolroom neatness and utilitarian signage. If you want ornate, calligraphic, or serifed results, this isn’t the right tool; if you want labels that look clean and readable, it’s spot on.

On the smallest sheets, line weight matters. Use a point that’s too broad and you’ll choke the negative space of characters like e and a. With a fine point, those same letters remain open and legible. On the 30 mm set, the inverse applies: too fine a line leaves the character looking wispy and unfinished. Pair the tool with the right instrument and you’ll get crisp results across the board.

Durability and care

After repeated sessions, I don’t see cracking or whitening along the edges—a common failure mode in brittle plastics. PET resists most classroom wear: banging around in a bin, the occasional bent corner, enthusiastic tracing from younger hands. The edges don’t curl.

Ghosting from alcohol-based markers is minimal if you wipe the stencil shortly after use. A spritz of isopropyl on a paper towel clears most residue. Acrylic paint flicks off once dry; I recommend a warm water rinse and a soft cloth rather than scraping, which can scuff the edges over time. Heat is not your friend—don’t leave these near a radiator or in a hot car and expect them to stay flat.

The set doesn’t include a storage sleeve. A zip bag or a thin document folder is a simple solution that keeps the sheets from collecting dust or bending.

Classroom and kids’ use

The “kid-friendly” claims line up with my experience. No sharp edges, no odor, and the bright colors hold interest. Younger users can quickly see where to place the pen thanks to the clear plastic, and the larger sizes are forgiving for little hands. The stencils also work well for practicing letter formation; tracing the same form repeatedly embeds the motion.

One note for teachers: the smallest sizes will frustrate students using thick pencils or markers. A cup of 0.5 mm mechanical pencils on the table solves that quickly, and it keeps the work neat.

Where this set shines—and where it doesn’t

Strengths:
- Four useful sizes that cover notebooks to posters
- Clear, sturdy PET with smooth, accurate cuts
- Easy alignment thanks to transparency and color tint
- Plays well with pencil, fineliners, markers, and stencil brushes
- Safe, classroom-ready construction

Trade-offs:
- Narrow apertures on the 8 and 10 mm sheets demand fine points
- Symbol set is limited to basics
- No storage sleeve or printed size labels
- Not as robust or ultra-precise as metal or pro-grade mylar for long-term heavy use

If you’re doing precise technical lettering on architectural vellum, or if you need ultra-thin, laser-cut mylar for masking and airbrushing, you’ll eventually outgrow a general-purpose PET set. Likewise, for exposure to harsh solvents or repeated industrial use, metal stencils are the better bet. But for craft rooms, classrooms, and everyday labeling, this set hits a sweet spot of convenience, performance, and price.

Tips for best results

• Secure the stencil with low-tack tape to prevent creep.
• Use a 0.3–0.5 mm pen for 8–10 mm letters; reserve thicker markers for 20–30 mm.
• Draw light pencil baselines; erase after the ink dries.
• For paint, dab rather than brush to minimize bleed.
• Clean marker residue with isopropyl and avoid scraping dried paint.

Verdict

The Bazic stencil set punches above its weight for general lettering, craft projects, and classroom practice. The four-size range is genuinely useful, the plastic is durable and clear, and the cuts are consistent enough to deliver neat, legible results with the right tools and a bit of care. The smallest sizes are best paired with fine points, and the symbol selection isn’t comprehensive, but those feel like reasonable compromises for an affordable, kid-safe set that covers so many use cases.

Recommendation: I recommend this set to teachers, parents, and hobbyists who want a reliable, budget-friendly way to produce clean lettering across multiple sizes without fuss. It’s particularly good for journaling, labels, posters, and early literacy activities. If your work demands an exhaustive symbol library, ultra-fine technical lettering, or pro-grade durability for heavy solvent or industrial use, look to specialized metal or premium mylar alternatives. For most day-to-day creative and educational projects, this is an easy yes.
