Joyclub 4 Pack Acrylic Lids Fit for 16 oz Glass Cups with Straws, Replacement Lid for Drinking Beer Glasses with Bamboo Lids Iced Coffee Cups Cute Tumbler Cup

A simple, mold-proof upgrade for can-shaped glass cups

I’ve cycled through more bamboo lids than I care to admit. They look great on day one, then swell, stain, and start to smell after a few weeks of iced coffee and fridge time. I picked up this 4‑pack of acrylic lids as a low-maintenance replacement for my can‑shaped glass cups, and after a few weeks of daily use, they’ve earned a permanent spot in my cabinet.

What you get

The set includes four clear acrylic lids sized for can‑shaped 16 oz and 20 oz glasses. Each lid is a flat, low‑profile disc with a central straw opening and a silicone sealing ring around the perimeter. They’re simple, transparent, and intentionally utilitarian—no wood grain or novelty going on here, just a clean look that matches most glassware.

A quick note on expectations: these are splash‑resistant lids, not leakproof closures. There’s an open straw port, so if you tip the cup, liquid will escape. The job of the lid is to keep dust out, hold a straw steady, reduce splashes, and give you a better seal to the glass than bamboo typically provides. On those counts, they do well.

Fit and compatibility

Sizing is the make-or-break with any replacement lid. These lids are about 2.7 inches across and intended for the can‑shaped glasses that have become popular for iced coffees, teas, and “beer can” style pours.

Here’s how they fit on the cups I tried:
- 16 oz can-shaped glasses: excellent fit. The seal engaged with a reassuring push, no wobble, and I could pick the cup up by the lid without it popping off.
- 20 oz can-shaped glasses from another brand: slightly loose out of the box. I swapped the perimeter O‑ring (silicone gasket) for a slightly thicker ring I had on an old bamboo lid, and the fit locked in perfectly.

That’s an important takeaway: small differences in glass diameter between brands matter. If you’ve got true can‑shaped cups, you’re likely fine, but “mason jar style” cups and novelty tumblers can vary. If your glasses run a hair larger, be ready to tune the fit by replacing or doubling the O‑ring; it’s a 30‑second tweak that can make a so‑so fit into a great one.

Two practical tips before you buy:
- Measure the inner diameter of your glass rim. If it’s much wider than 2.7 inches, look for a different size.
- If you’re replacing bamboo lids that worked “well enough,” keep those gaskets—they’re handy to tune these lids for a snug fit.

Build quality and materials

The lids are molded from clear, rigid acrylic. Compared to bamboo:
- They don’t absorb flavors or odors.
- They don’t stain with coffee or tea.
- They don’t swell, warp, or develop mold.

The silicone ring is the hero here. It provides the friction and seal against the glass wall. It’s removable for cleaning, retains its elasticity after dishwashing, and has enough give to accommodate tiny variations in glass diameters.

Acrylic has its own tradeoffs. It’s tougher and less scratch‑prone than many plastics, but it’s still plastic—avoid abrasive scrubbers that can haze the surface over time. Heat is not acrylic’s friend, either; I treated these as cold‑drink lids only.

As for cleaning: I ran them on the top rack of the dishwasher multiple times with no warping or clouding. If you hand‑wash, pop off the silicone ring occasionally to clean underneath—coffee oils and citrus residue like to hide there.

Straw compatibility

The straw port is centered and chamfered, and it handled every straw I threw at it: skinny metal straws, standard glass straws, and floppy silicone straws. It’s not a tight gasketed port; the straw sits neatly but isn’t “locked” in place. That’s normal for this style of lid, but it’s worth noting that if you jab a thick glass straw at an angle, you’re leveraging against the lid. On cups where the seal is loose, a hard bump on the straw can dislodge the lid. Again, a snug fit solves that.

If you favor very wide smoothie or boba straws, check the diameter of your straws against the port. Mine fit, but extra‑wide straws are hit‑or‑miss on this lid style in general.

Day-to-day use

Functionally, these lids do exactly what I want from a daily driver:

• Seal: On a good-fitting glass, the seal is satisfyingly snug. I gave a full 16 oz tumbler a shake over the sink; the lid stayed put, and there were no splashes around the rim. Obviously, the straw hole is open, so it’s not spill‑proof, but the lid’s grip matters when a cup gets knocked.
• Clean taste: No trace of yesterday’s cold brew or lemon water. That’s a refreshing change from bamboo, which tends to keep souvenirs.
• Condensation control: The flat profile helps keep drips off the rim and down into the cup, so you don’t get that ring of moisture right where your lip meets the glass.
• Fridge duty: With water or tea in the fridge, the lids keep odors out and dust off. I like that I can see through the lids at a glance to check what’s inside and how much is left.
• Aesthetics: Clear lids disappear into the look of the glass. If you’re into color‑coordinated setups, these are plain enough to match whatever straws you pair with them.

What could be better

• Tolerance wiggle room: A single O‑ring spec can’t fit every “16 oz/20 oz” glass on the market. Including a second, slightly thicker gasket in the box would solve most fit complaints without asking users to go hunting for replacements.
• Straw port options: A removable silicone grommet around the straw hole would add grip, dampen straw rattle, and slightly improve splash resistance—all without complicating the lid.
• Size labeling: Clear, printed size guidance (“2.7 in rim fit”) on the lid or packaging would reduce guesswork for folks mixing brands and styles of cups.

None of these are deal‑breakers, but they’re easy wins that would make the lids more universally satisfying.

Who it’s for

• People replacing bamboo lids that have warped, stained, or gone musty.
• Anyone using can‑shaped 16 oz or 20 oz glass cups for iced coffee, tea, infused water, or cocktails.
• Households that want low‑maintenance, dishwasher‑safe lids they don’t have to baby.

Who should look elsewhere:
- If your cups are wide‑mouth mason jars or have nonstandard rims, these likely won’t seal well. You’ll want lids made specifically for those dimensions.
- If you need leakproof transport (bags, commutes, kids tossing cups around), look for lids with sealed straw ports or fully closed tops.

Care tips

• Dishwasher: Top rack worked well for me. If your dishwasher runs very hot, let them cool before popping the lids off a glass—hot acrylic is more flexible.
• Hand‑wash: Use a soft sponge and mild detergent; avoid scouring pads to keep the surface clear.
• Gasket maintenance: Remove the silicone ring weekly and rinse underneath. If the fit loosens over time, warm the ring in hot water and reinstall, or replace it with a slightly thicker O‑ring.
• Storage: Store lids dry. Acrylic won’t mold, but the silicone ring will last longer if it isn’t left damp in a stacked pile.

The bottom line

These acrylic lids are a practical, low‑maintenance upgrade for can‑shaped glass cups. On standard 16 oz glasses, the fit is excellent; on some 20 oz glasses, a quick gasket swap dials in a firm seal. They’re cleaner, more durable, and more hygienic than bamboo, and they maintain a minimal look that suits everyday use.

Recommendation: I recommend them for anyone frustrated with bamboo lids or looking to outfit a few can‑shaped glasses with something sturdier and easy to clean. Just measure your glass rim first, and be prepared to tweak the gasket if your cups run a little large. If you need a leakproof solution or have wide‑mouth mason jars, this isn’t the right lid, but for typical 16 oz/20 oz can glasses, they’re a simple win.
