This is a set of a belly band and an abdominal support belt. The pink one was purchased several years ago, and the gray one was purchased and used in February of this year. The pink one is size M-L, and the gray one is L-LL, but I was able to use the pink one until close to my due date, even though my belly was quite large. Would you like to have them as a set for washing and changing? They show signs of use, so please consider purchasing if you understand that they are used items. Pink: Inujirushi Honpo Gray: Pigeon
