Set of two maternity mark straps ☺︎ I apologize, but the blue one does not have a chain. However, it does have a place to attach a chain! Also, the text on the back is smudged. Please check the second photo. I will wrap them to prevent them from getting wet and send them via regular mail. I found it convenient to have several because it was a hassle to switch them between different bags, so I'm offering them for sale ☺︎ #baby #pregnancy #childbirth #keychain #strap #AkachanHonpo
