These were given to me when my child was born, but I haven't used either of them. Blue: 31cm (height) x 34cm (width), no gusset, total length of the string is 51cm. White: 31cm (height) x 33.5cm (width), no gusset, total length of the string is 51cm. Although they are unused, please understand that they have been stored by a private individual. Thank you very much.
