Pour a drink that still tastes like the drink at the bottom of the tumbler. One large tumbler-shaped ice piece sized for a 40oz cup chills your drink slowly, so the last sip is as strong as the first. Fill, freeze and release it from the two-piece silicone mold.
Makes large tumbler-shaped ice that fits a 40oz cup and keeps drinks cold without watering them down
- ice melting too fast in large tumblers
- bland drinks diluted by small cubes
- hard-to-release ice shapes
One big cube that keeps your drink strong
Tiny cubes melt into a watery mess before you finish your tumbler. This mold makes one large tumbler-shaped ice piece that chills your 40oz drink without diluting it.
One Large Cube Shaped to Fit Your Cup
- Fits a 40oz tumbler
The ice piece measures 18.7 x 7.9 x 5.65 cm, shaped to sit in a 40oz tumbler. One piece fills the core of the cup and keeps the drink cold longer than a handful of cubes.
- Clear, fruit-filled ice
Drop berries or strawberries into the cavity before freezing. The ice comes out clear with fruit suspended inside, which makes a plain iced drink look deliberate.
- Easy release
Side notches and a handle cutout give you grip points to push the ice out. Let the tray rest a few minutes at room temperature and the piece comes free without cracking.
From Tray to Tumbler in Three Simple Steps
- 1Fill through the top hole
Pour water into the cavity through the fill hole until it reaches the level of the vent. Leave a little room at the top so the ice has space to expand.
- 2Freeze fully
Set the mold on a flat shelf and freeze overnight. Fully frozen ice releases cleanly and holds its shape in the drink.
- 3Release by the ridges
Let the tray sit a few minutes at room temperature, then press the side ridges and use the handle notch to ease the piece out. Drop it into your tumbler and pour.
Two Pieces, One Big Ice Upgrade
- Silicone ice mold tray×1
Tumbler-shaped cavity with fill and vent hole
- Lid×1
Covers the tray while the ice freezes
Small Cubes Leave You Watery Sips

The Last Cube Problem
Small cubes disappear fast in a big tumbler. By the second hour the drink tastes like melt, and every refill means another tray of tiny cubes to pop out and watch vanish.

One Big Piece Changes It
This mold makes a single tumbler-shaped piece sized for a 40oz cup. A large mass melts slower, so the drink stays strong from the first sip to the last without a constant top-up.

Ice That Looks as Good as It Chills
Clear ice with berries suspended inside looks deliberate in a glass. Serve it at the patio table and the ice becomes part of the drink.
How Big the Ice Really Is

- 11.2 cmMold width
- 6.2 cmMold height
- 18.7 cmIce piece length
The finished ice piece is 18.7 cm long, sized to drop into a 40oz tumbler.

Questions and answers
The cavity is shaped for a 40oz tumbler, and the ice piece measures 18.7 x 7.9 x 5.65 cm. If you use a different cup, check its opening against the 7.9 cm width before you assume a fit.
It is built around the 40oz size. Smaller cups can take the piece, but the mold was shaped for a tumbler, so a large glass or pitcher will get the most out of it.
Freeze fully, then let the tray sit a few minutes at room temperature. Press the side ridges and use the handle notch. Skip sharp tools, which can crack the clear ice.
Yes. The soft matte silicone stays flexible in the freezer, and the lid keeps the cavity covered while the water sets.
One piece replaces the stack of small cubes you would refill through an afternoon. The tray and lid together make a reusable setup that lasts through many batches, so the cost per drink drops with every use.
