## Questions & Answers

**Q: Are these hard to click into connector?**
A: They don't actually "click" on to the connector.  The connector fits snugly into the sturdy straw pieces.  They're easy to connect, and stay together until pulled apart.

**Q: Happy Holidays. How many straws are there from the 800 pc set?**
A: Too many to count.  My granddaughter makes things out of this set all the time but they are not sturdy enough to make a fort with a sheet cover.

**Q: Are they sturdy enough for rough kids?**
A: Yes they are. My kids are rough and none have broken.

**Q: Does it come with a storage bin?**
A: Ours did not but it did come with a plastic zipper bag that stores them all perfectly and has lasted for years now.
