Product review
What you get: one 20 oz single-walled glass tumbler, a clear Tritan plastic lid that quarter-turns onto the glass’s internal threads, a thick reusable straw, a removable soft silicone sleeve for grip, and a silicone base that quiets set-downs and adds slip resistance.
Materials and construction: The cup body is single-walled clear glass so your drink is visible — ideal for iced lattes, cold brew, matcha, smoothies, and other chilled beverages. The lid is made from clear Tritan plastic and locks onto internal threads in the glass with a quarter-turn motion for a snug fit. The straw is thicker than typical disposable versions to deliver a smooth draw. A soft silicone sleeve covers the glass side for a comfortable hold, while a thicker silicone base cushions contact with counters and helps reduce rattling in cupholders.
Size and fit: The 20 oz capacity strikes a balance between everyday use and portability. The slim lower profile was designed to slide into most car cupholders and to sit stably on desks and kitchen counters without wobbling.
Performance and use: Because the body is single-wall glass it won’t provide vacuum insulation — ice will melt faster than in stainless steel, and condensation can form on the exterior during extended cold use. That same glass construction, though, prevents flavor transfer and shows off the drink’s layers and color. All components — glass, lid, straw, sleeve, and base — are dishwasher-safe, so the cup is easy to clean between uses.
Practical points: The quarter-turn, internally threaded lid gives a more secure seal than a friction-fit cap, and the thick straw is reusable and comfortable. The silicone sleeve helps protect hands from cold and adds grip, while the base softens contact and limits noise and sliding. It’s presented as a reusable alternative to single-use cups and makes a considerate gift for those who enjoy cold beverages.
Who it’s for: Choose this tumbler if you want an attractive, dishwasher-friendly glass cup for iced drinks and care about showing your beverage. If you need long-lasting temperature control or a fully leakproof travel mug for long commutes, an insulated steel model may be a better match.
Pros
- Clear glass displays drink layers and color
- Dishwasher-safe components for easy cleaning
- Fits most car cupholders and has a quiet silicone base
Cons
- Single-wall glass — not insulated, so ice melts faster
- Can develop exterior condensation during cold use
- Some users report lid sealing issues on certain units
VerdictThis single-walled 20 oz glass tumbler is ideal if you want a stylish way to show off layered cold drinks and avoid plastic flavor transfer. It’s dishwasher-safe, cupholder-friendly, and offers a comfortable grip, but it won’t keep beverages cold like insulated metal tumblers and can develop condensation.

Pretty and travel-friendly
Handy 20 oz size that’s easy to carry. The color is attractive and the glass feels more refined than plastic. The straw lid prevents many spills and the shape fits cupholders comfortably.

Customer 5/5
Solid everyday iced coffee cup
The beige glass is thicker than expected and the sleeve provides a good grip. It’s single-wall, so ice melts and it can sweat — use a coaster.

Customer Review 5/5
Sturdy, easy to keep clean
I like the muted green color and how easy it is to clean in the dishwasher. The glass feels solid and survived a few knocks without chipping.

Condensation makes it messy
Bought it for iced coffee and the ice melted quickly, thinning the drink. Condensation pooled on the outside and left wet spots everywhere.

Lid failed and caused a spill
After washing it the lid wouldn’t tighten the next morning. I spilled coffee everywhere and had to change clothes — very frustrating experience.

Nice grip and secure twist lid
The silicone sleeve feels great in hand and the screw-on lid gives confidence when carrying. Simple and pleasant to use.

Too much sweat and some leaking
I own several similar cups but this one produced a lot of condensation, had a leaking issue, and didn’t keep drinks cold. Cute look but too clammy for me.

Exactly the glass tumbler I wanted
I love this cup — it’s dishwasher-safe and perfect for my desk. The glass is clear and it keeps me sipping water all day long.
