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

Swell water bottles have a slim neck opening and look more like a glass bottle than the typical largemouth water bottles. The slim ice cubes fit almost perfectly. When you fill any ice try each cube will be a different size of course. If the long ice cube does not fit perfectly, I place it in the bottle mouth and run tap water down the side. This melts the long ice cube, and it slips into the bottle. This works for me!!! All of our ice cube trays are silicone. Easy to fill and remove the ice. We will NEVER purchase another metal or plastic ice cube tray.

They're pretty good except for their little flimsy so I have to set them in the freezer then pour the liquid in them could be a little bigger which would really be nice

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.

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.

These silicon ice trays fit easily into the small fridge my son has in his dorm. They fit perfectly into the tiny freezer. Removing the ice into a water bottle is very easy due to the flexibility of the silicon. The ice fits into the water bottle easily. Having three in the set means there is always two full of ice while another is still freezing.The review preview asked about taste, but there is literally no taste transferred to the ice or water in the bottle.

Not a bad product but I do wish it was stackable.

Keeps drinks colder when you use these in a water bottle with a straw

These fit into the water bottles perfectly. A bit messy to fill but worth it.
