Product is fine. However, my eyesight on computers is so poor I cann't read desciptions and guessed at the size. I guessed too small for my intended use. [Holding not a coin, but a "Grabber" brand hand warmer using the pouch on the inside of a nightcap to warm a low-grade recurring TMJ problem with my right jaw. The pouch is about 1/4" too short to fit the Grabber hand warmer. My fault, not the product, which is great!
