Thank you for viewing. A back support belt made with breathable mesh material. - Model Name: MAXBELT me2 - Size: S - Color: White - Material: Mesh It has been stored at home for a long time without being used. I feel that there is some slight discoloration from storage. There is no deterioration of the rubber. Please refrain from purchasing if you are sensitive to this.
