Webake Silicone Ice Cube Trays for Water Bottles Ice Cube Mold 12 Cavity, Easy Release Long Ice Cube Sticks For Bottled Beverage, Soda, Sport Drinks, Burritos Egg, Pack of 3

In comparison to molds made specifically for pen blank casting, these are a bargain. They should work perfectly. Can’t wait to cast some blanks in these this weekend.

I love to use these cubes in my water bottles. I put in 4 cubes and my bottle is good to go!

This is a simple item, and requires only a simple review: it works, but isn't quite perfect. It produces square rods of an excellent size for cooling bottles of varying dimensions - I use them for large and medium Yeti, Contigo, Hydro Flask products. That said, they are quite a challenge to successfully carry from the sink to the freezer. It's REALLY easy to spill, and the trays don't have any rim reinforcement, so they do flex a bit, compounding that issue. Once the ice is frozen, it take a bit of work to get them to pop free, as the water obviously expands in the tray. For this reason, and the aforementioned spilling, I suggest filling them about 3/4 full, them moving them to the freezer. I don't regret the purchase, and they're doing the job I required them to do, but be aware of these concerns when evaluating your purchase.

Used these for doggy popsicles. They work great as they make the ice cubes long and thin enough that they thaw quickly and are easy enough for the pups to chew them up without damaging their teeth. The flexibility makes it easy to clean and empty the popsicle ice cubes out into a bag for easier access.

These ice cubes are really cool and they keep for a pretty long time

The ice trays are NOT braced. So they are kind of flimsy to move to the freezer, therefore spilling water. I’ve tried a couple different methods to move them but they spilled each time… However, the ice shape itself if very nice and the ice cubes stay frozen in my bottle all day long!

Tip - I put a small plastic cutting board on my freezer shelf, then put the empty ice trays on it. I then fill up a glass measuring cup with filtered water and pour it in each tray slot. This cuts down on spilling water everywhere.

Update - So dont try to stack them like traditional ice trys. The freeze together and make ot difficult to pry them apart. Works as it should. Simple and easy. Convenient size that fits perfect in my freezer. Makes perfect long cubes for my wife and kids water bottles.

I found the perfect water bottle but the only downfall was the skinny top opening. These ice cubes work perfectly in those skinny top bottles, easy to remove from the tray and the ice freezes really fast. These are perfect size yet thick enough they don’t melt fast.

a little smaller than I thought but a great product. Ice is easy to fit in any size water bottles.

Cumplen con su función, el silicón es bueno pero los hielos salen muy delgaditos

We purchase these to create Pen Blanks for turning from epoxy. The "proper' molds were very expensive and this is a great alternative. You end up with a blank that is approximately 22x22x150mm. And because each mold does 4 and this has 3 molds, this is really cost effective.

This makes long narrow ice cubes which are great for putting in water bottle to cool your drinks.
