Why standard cubes are the wrong shape for a big tumbler

A 40 oz cup has a narrow mouth and a lot of height. Cubes wedge sideways at the opening, block the straw, and take up volume that should be drink. Cylinders are shaped like the cup itself: they drop straight to the bottom and stack vertically instead of jamming.

The long shape also has less surface area touching the drink than the same volume of small cubes, so melting slows down. For water, iced coffee

Medium cylinders for 30 oz cups

Tall cylinders for 40 oz tumblers

One integrated tray, filled in a single pour

You fill the whole tray at once, freeze one batch, and pick the right size for each glass. No second tray, no spare parts, no guessing which mold fits a 30 oz cup.

How to use it

Fill the cavities with water or your drink of choice, close the lid firmly, and set the tray flat in the freezer. takes about four to six hours to freeze solid. When it is ready, let the tray sit for two minutes, then press the bottom of each cavity to release the ice.Cylinder ice

Drop one or two cylinders into your tumbler before filling it with coffee, cold brew, or water. Because they melt slowly, you rarely need to fill the cup with ice to keep it cold.

Standard cubes versus cylinder ice

A standard cube tray fills a 40 oz tumbler with ice that blocks the straw, sloshes when you walk, and melts into weak flavor by lunchtime. Cylinders stack vertically, leave room for the drink, and melt from the outside in at a slower rate.

Matching ice size to your cup

Use the shortest cylinders for 20 oz cups and travel mugs, the middle size for 30 oz cups, and the tallest for 40 oz tumblers. When you are unsure, shorter is easier to work with because you control the fill level.

Wide-mouth cups accept all three sizes. If you use a straw lid, drop the cylinders in before adding the drink so they settle at the bottom instead of floating.

Questions people ask about these trays

Will the cylinders fit my cup?

The three sizes are designed for standard 20 oz, 30 oz, and 40 oz tumbler openings. Check your cup height and pick the matching length.

Is the silicone safe for food?

Yes. The mold is food-grade silicone, BPA-free, and safe for direct contact with ice and beverages.

Is this an official Stanley product?

No. It is a compatible tray made to fit the common tumbler sizes, not a Stanley-branded accessory.

How do I clean it?

Rinse under warm water or place it on the top rack of the dishwasher after removing the lid.

How many cylinders should I use per cup?

Start with one or two, depending on cup size and how cold you like your drink. Because they melt slowly, you rarely need to pack the cup.

If your tumbler goes to the office, the gym, or the car every day, this tray removes the biggest annoyance of using it: ice that waters down your drink. Freeze a batch tonight and tomorrow's cup stays cold and strong until the bottom.
