Number of wears: The 70cm one was worn once. The 50-60cm ones have only been washed and are too small. The size is the same as the 70cm one, and the 50-60cm ones are made larger. I am selling them because my next child is a girl. .:. * ・ ゜ ☆ They have been stored at home. I hope they reach a cute baby boy! + ゜. * (´∀｀*) * . ゜ +
