## Questions & Answers

**Q: Can these be boiled? Mine is losing its shape and so the ends are pinching me bad.**
A: I boiled mine to sanitize them when I first got them. Seemed fine.

**Q: If i measured 15mm would these be correct or should i purchase a 17mm insert?**
A: I believe it depends on which pump you are trying to get. Willow needs exact sizing, I’ve heard to go up in spectra. I bought 15 and 17 and use whichever one was more comfortable, which was the true to size, 15s. Hope that helped!

**Q: If anyone used these with momcozy s9 how well did they work??**
A: They work very well. I used them in the 24mm momcozy

**Q: Will these work for the momcozy ?**
A: Yes they do
