This is a set of two white, size M arm covers with a cooling effect. I purchased these about 3 years ago. I used them once, but the size didn't fit, so I washed them and put them away. I think they are in good condition, but the rubberized non-slip dots on the inside of the upper arm area have yellowed. I only used them once, so it seems the discoloration is due to storage. These have been stored at home for a long time. Please refrain from purchasing if you are concerned about this. If you don't mind, please consider them. - Product Name: COOL ARM COVER - Size: M - Color: White - Quantity: Set of 2 Thank you for looking.
