    • Perfect to renew good thermos water bottles
Size: 2 Pack
Makes water bottle new again. Easy to clean and quite durable. Only had to change because child went through a biting phase but with normal use these will last a long time.

    • Perfect
Size: 2 Pack
Excellent quality, fits perfectly, so glad these are available as just the straw replacement instead of needing to buy a whole new bottle.

    • Good repurchase
Size: 2 Pack
Buy these every 6 months. Kids chew on the straws and its nice to replace rubber straw instead of keep buying water bottles for school!

    • Definitely recommend buying these when you buy a cup
Size: 2 Pack
Always trying to find these in stores and they're sold out. These are great because my family has like a zillion cups and sometimes we misplace or break the straws.

    • Saves buying a new bottle
Size: 2 Pack
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.

    • Missing parts
Size: 2 Pack
Tried to cancel the order after we made it because the straws are bad. My kids chewed right through them and thats a danger so i was scared to keep them. It wouldnt let me cancel it because it already shipped. I planned to return them as soon as we got it. Then this arrived with only one box of 2 straws even though we paid for 4. I cant even return it because we didnt even get what we paid for! ... show more
