These fit the 12oz Funtainer exactly like the original. The silicone parts are easy to swap out and wash when they get worn. Simple and practical.

I mean they did what they needed to do. Perfect fit! Nothing special but hopefully I don’t need to buy more soon.

    • Worth it!
Size: 2 Pack
These are the perfect match for the thermos funtainers that we use every day. The straws are durable, but my kid (3 yo) gnaws and chews all straws. These replacements are a good price, I don't mind buying a replacement pack every month.

    • Easy way to keep favorite bottles going
Size: 2 Pack
My kids use their water bottles constantly throughout the day, so having replacement straws on hand has been surprisingly helpful. After months of school lunches, soccer practice, and being tossed into backpacks, the original straws started looking worn out. These replacements fit nicely and gave the bottles a fresh feel again without needing to replace the entire bottle. I liked how simple it was to swap everything out in just a few minutes during kitchen cleanup. The silicone portion feels soft and comfortable for younger kids to drink from, which matters in our house because my younger child can be picky about textures. The straws stayed flexible even after repeated washing, and they did not develop any strange odor over time. I also appreciated that the pieces felt sturdy enough to handle daily use without constantly bending out of shape. Cleaning them was easier than I expected. I usually rinse them right after use and occasionally place them in with the rest of the bottle parts during deeper cleaning days. Having extra pieces available has been convenient because I do not have to panic if one accidentally disappears during a busy week. With children, small bottle parts somehow seem to vanish regularly, so the extras came in handy faster than expected. ... show more
