### ⭐⭐⭐⭐⭐ Cute and necessary

### ⭐⭐⭐⭐⭐ Silicone flower straw caps (pack of 6) fit Hydroflask
*by S***8 on June 4, 2026*

Cute little flower silicone straw caps. There are 6 random colors and they fit my Hydroflask. Not overly easy to put on the cap one-handed because the straw is flexible and wants to bend when you try, but it can be done. Or you can just use two hands while the mug is sitting on a table or counter to make it easier. I think having a cap helps the ice to last longer, plus the obvious thing, to keep it clean. I wish the colors were a little closer of a match to my cup, but they work and are still cute. I would recommend if you want something inexpensive to help keep your liquids cold and the straw clean.
