ZJWZSLI 120 PCS Reflective Mailbox Number and Letters Stickers, 2 inches Self Adhesive Capital Letter Sticker, Reflective email digital sticker, suitable for Pre-Spaced Waterproof for Mailbox Address, Bin,

I replaced the fading address decals on my mailbox and garbage bin with a pack of 2-inch reflective stickers from ZJWZSLI, and I’ve kept a close eye on how they perform through daily use and a few weeks of mixed weather. They’re a simple product—numbers and letters on adhesive vinyl—but a few details make the difference between a tidy, readable result and a frustrating application. Here’s how they fared.

What’s in the pack

You get a total of 120 characters: a mix of numbers (0–9) and capital letters (A–Z) in a 2-inch height, all in white reflective material. The characters are die-cut on multiple sheets. There’s no transfer tape or spacing guide included; you peel each character off its backing and apply it individually.

Important to note: this is a straightforward set meant for DIY labeling. It doesn’t include duplicates tailored to specific addresses, so if your house number or name uses a lot of repeated letters (hello, E and S), plan your layout before you start—or consider ordering two sets if you need both sides of a mailbox or multiple surfaces.

Material and build quality

The characters are thin, flexible reflective vinyl (PET). Thinness is a double-edged sword here: it helps the stickers conform neatly to slightly curved surfaces, but it also means you need to handle them with care when peeling. I found that starting the peel with a craft knife or a pair of tweezers at a corner reduces the risk of stretching or nicking the edges, especially on angular shapes like A, M, and N.

The white reflective finish is bright under headlights and flashlights. In daylight, it reads as matte white. On dark surfaces, it’s high-contrast and clean; on light or white surfaces, readability in daylight is less pronounced, though the reflective effect at night still helps.

Installation experience

I tested the stickers on four common surfaces:
- Powder-coated metal mailbox (curved door)
- Smooth glass panel near the front door
- Painted wood (semi-gloss)
- Textured plastic garbage bin

Preparation matters. I cleaned each surface with isopropyl alcohol, let it dry, and did a quick pass with a microfiber cloth to remove dust. For alignment, I used low-tack painter’s tape to create a baseline and dry-fit spacing. Because there’s no transfer tape, you’ll place each character manually. The “hinge method” (taping a paper guide in place and using the tape edge as a reference) helped keep the line straight.

Adhesion on smooth surfaces was immediate and strong. These are not repositionable; once they grab, you can get a small amount of wiggle room for a second or two, but trying to lift and re-seat often distorts thin strokes. Pressing firmly with a plastic squeegee (or the edge of a credit card) set the edges well. The instructions recommend giving the adhesive up to 24 hours to fully cure; I’d echo that, avoiding washing the surface or exposure to heavy rain during that period if possible.

On the textured bin, adhesion was okay, but not as confident. The letters went on cleanly, yet the microtexture means less contact area. I warmed the surface slightly with a hair dryer and pressed again—this improved edge seal and prevented minor lifting at the corners.

Visibility and reflectivity

At night, the reflective effect is excellent. From a driver’s perspective, the numbers popped clearly under low-beam headlights from about 50–70 feet, which is plenty for delivery drivers to identify the address without creeping to a stop. On a dark green mailbox, the white characters are readable even before the retroreflective kick-in.

In daylight, the 2-inch size is serviceable for suburban settings where the mailbox sits close to the road. If your house is set back or you want visibility from farther distances, 3–4 inches would be better. Also consider background: white letters on a white or silver box are not ideal in daylight. If your surface is light, a contrasting backer panel or choosing black lettering (not included in this set) will be easier to read.

Durability so far

After a few weeks of rain, morning dew, and direct sun, the stickers on metal, glass, and painted wood show no lifting or discoloration. Edges are intact, and the reflective finish hasn’t dulled. On the textured plastic bin, the characters remain adhered, though I can feel a slight “lip” at a couple of corners. It’s not peeling, but it’s the first place I’d expect wear to show after months of use. The PET material seems to resist grime and wipes clean with a damp cloth.

Given the thin profile, abrasion will be the enemy. If your bin rubs against rough surfaces or gets pressure-washed frequently, expect faster wear. On mailboxes and smooth doors, I’d anticipate a longer life.

Things I liked

• Clean, bright reflectivity at night, noticeably better than non-reflective vinyl.
• Strong tack on smooth, non-porous surfaces once cured.
• Thin profile conforms well to curved metal mailbox doors.
• Simple, no-frills value pack suitable for multiple projects.

Where it comes up short

• No transfer tape or pre-spaced strips. Alignment and consistent spacing are entirely on you.
• Characters are thin; they can stretch or tear if peeled aggressively. Tweezers are your friend.
• White-only color limits daytime contrast on light-colored surfaces.
• The assortment of letters may not cover repeated vowels or consonants for longer labels without buying an extra pack.
• 2-inch height is adequate for most mailboxes but may be undersized for long setbacks or local code requirements; check regulations before you commit.

Tips for best results

• Clean with isopropyl alcohol and let dry completely.
• Create a straight baseline with painter’s tape and lightly mark spacing with a removable pencil or chalk.
• Use tweezers or a craft knife to lift corners; avoid bending thin strokes.
• Apply firm, even pressure with a plastic squeegee to set edges.
• Warm slightly with a hair dryer on textured plastics to improve adhesion.
• Let the adhesive cure 24 hours before washing or heavy exposure to the elements.

Who this set suits

These reflective stickers make sense if you:
- Need a quick, low-cost way to refresh mailbox numbers or label bins and doors.
- Have dark, smooth surfaces where white reflective characters will stand out day and night.
- Don’t mind doing your own alignment and spacing.

If you want a perfectly professional look with minimal fuss, a pre-spaced vinyl kit with transfer tape or a larger, single-piece reflective plaque will save time and reduce alignment errors. And if your address must meet a specific character size in your area, verify that 2 inches is compliant.

The bottom line

The ZJWZSLI reflective stickers deliver exactly what I needed for a clean, reflective address on a dark mailbox, and they’ve held up well through wet mornings and direct sun. Installation requires a bit of patience and a steady hand—these are individual characters, not a pre-spaced system—and the material’s thinness rewards careful handling. On smooth metal and glass, adhesion is strong; on textured plastics, a bit of heat and pressure helps.

Recommendation: I recommend this set for budget-friendly, DIY labeling on smooth, dark surfaces where 2-inch white reflective characters will be visible and compliant. Buy two packs if you anticipate lots of repeated letters or need to label multiple sides. If you prefer a larger size, need better daytime contrast on light surfaces, or want the convenience of pre-spaced transfer, consider alternative kits—but for straightforward mailbox and bin projects, these stickers get the job done reliably.
