## Questions & Answers

**Q: What are the dimensions of this item B?**
A: Three or four inches, roughly

**Q: is this the right size for pinky?**
A: These come in at least two sizes. Probably best if you get fitted by an o Occupational Therapist.

**Q: where is the measurement information to pick a size?**
A: If you look at the display on Amazon, right after the name of the product you will see "AA." That is the size. They range from AA to A to D. Here's what one purchaser wrote, based on language on the packaging when the product was delivered: I, "Measured from palmar crease to distal finger crease." specifically on my left pinky finger, did exactly as told to do, and got (give or take 1/16") 2 1/2"; wherein I purchased this size. After receiving the product and reading the packaging/instructions it clearly indicates that AA is 2 1/4" and A is 2 3/4"

**Q: What is the difference between size a and size aa? i need one for my little (pinky) finger**
A: I had the same question, so I bought both an A and an AA. For a pinky finger, especially for a woman, the A is too large. Get the AA. I returned the A.
