Our Take
Smart design solves a real tumbler problem at a fair price.
These aren't regular ice cubes—they're engineered hollow cylinders that match your tumbler's interior and melt slower. The set includes three different-sized ice molds (outer diameters 2.4 inch, 2.8 inch, and 3.34 inch) so you can customize for 20, 30, or 40 oz cups.
The Buying Guide
What to look at before you buy
01
All three ice cubes are 2.8 inch height and 0.47 inch thickness with staggered outer diameters.
Size & Fit
The first two stack for 20–30 oz tumblers; all three work for 40 oz. The hollow cylinder design is the real win—more surface area in contact with your drink means slower melting and less watered-down sips over time.
02
Food-grade, BPA-free, odorless silicone with removable lids.
Material & Durability
Thick silicone construction promises longevity, and the leak-free design keeps your freezer tidy. Lids stack the molds compactly and protect ice from freezer odors, while the whole thing is dishwasher-safe for low-effort maintenance.
03
Pour water, cover with lid, freeze, then twist to release.
Operation
Dead simple—though the instructions note waiting 20 seconds or running warm water around the tray if ice sticks. That's a minor extra step but standard for silicone molds and not a friction point for 4.3-star users.
