Review: Get the boon accessories you won’t regret it. - These work so well! They do not spill or leak. I have not had it fall from more that 3ft. Probably the most leakproof cut I’ve ever had. I like the fact that I don’t have to buy a whole cup set but instead have the option to buy just the lids. This is economical choice as well as an environmental one. I started with bottles then sippy cup and now this one with a straw. I also have flat lids for storing their snacks. So I feel less wistful and more money on my pocket with the boon system that growers with them. However they are a little tough to drink out of. I tried it because my baby was having difficulty but within a few minutes she was fine. Overall great fit use and easy to clean.

## Questions & Answers

**Q: I have the 4 oz bottles, can i just cut the straws to fit or is there another shorter straw conversion set?**
A: They don’t make straws for the 4oz bottles since the smaller size is generally used for younger infants. The straws have bite valves at the top so are more suitable for 9months + of age for which a child is usually using a larger bottle.

To answer your question - technically you could cut the straw.

**Q: Can this fit mason jars ?**
A: No, the threads are different.

**Q: Is this a direct match for the grey boon nursh?**
A: the straw top fits all of the silicon pouch bottles (4 and 8 ounce or all colors). Our daughter loves them and it makes the bottles usable for a lot longer.

**Q: Am I wrong Description states 2 pack but was only one in package**
A: It should be two

### ⭐⭐⭐⭐⭐ Great next step!
*by E***E on 6 February 2025*

These are great!! Having already had the Boon bottles from my baby registry, these are a perfect upgrade for baby who’s ready to move to sippy cup style! Love that they are a valves straw so no backwash and graduated drinking which allows for baby to not choke on water as they learn. Mostly spill proof though some does leak out of the straw a little but has been dropped on the floor and tipped upside down multiple times and doesn't spill! As an OT mama I love this option in place of a standard sippy cup
