This is a mask case for children. It's for temporary storage when going to school or going out. ^ ^ Masks of 12.5 x 8cm size will fit. It's the perfect size to fit in the larger mobile pocket I'm selling. Size: 10cm tall x 11.5cm wide Snap button: 13mm If you like any of the fabrics I'm selling, I can make one for you, so please comment. (I may decline if the fabric is out of stock) Basically, it will be sent by standard or non-standard mail, so it may take some time. Thank you for your understanding. (There is no tracking or compensation) Changes to the shipping method are negotiable (additional charges apply) +¥150 for Rakuraku Mercari Mail Nekopos +¥100 for Yu-Packet Post Mini
