## Questions & Answers

**Q: how do you size?**
A: After I purchased the medium size, I found the manufacturer's sizing chart on its website.  I ordered two sizes too small.   I normally take a large size men's leather glove, and I found I should have ordered the large for this as well, but by then I had used it and inserted the plastic splint into a microwave to bend it to shape, and I felt it was not appropriate to try to return it.  The instructions state that once inserted and hated in the microwave, the plastic splint can't be removed.  I was able to get it out,  but the heating process had left permanent fabric markings and indentations on the splint.

**Q: What materials are used in making this?**
A: I know it has some polyester and neoprene for stretching.  This is the ones Ortho doctors use.  I don't know what other materials are in it

**Q: Why is the right small plus $10 more than any other size?**
A: I don’t  i needed a med send note to owner/ manufacturer

**Q: What is the return policy on this item?**
A: Not sure since I kept it. Read the small print. I would assume it’s the standard Amazon return policy.
