The pocket has a 2cm gusset. A gauze handkerchief of about 20cm square can also fit. This size is suitable for kindergarteners to lower elementary school students. To make it easy for young children to open and close, no fasteners are used on the flap (lid). Adhesive interfacing is applied to the flap. The weight of the flap makes it less likely to open easily. 【Notes】 The clips, handkerchiefs, tissues, miscellaneous goods, etc. in the photos are not for sale. Please hand wash or use a laundry net. Do not use a dryer. If the flap wrinkles after washing, ironing will restore the fabric's firmness. Due to being a handmade item, there may be some unevenness or misalignment in the stitching. Please understand this before purchasing. When playing in parks or on playground equipment, please remove the pocket to prevent accidents. Please wear it with sufficient attention to safety. Shipping is planned via regular mail. If you prefer anonymous shipping, please comment before purchasing. Anonymous shipping is available for an additional fee of 150 yen. <Materials> Outer fabric: Cotton print Lining: Cotton print *The pattern of the printed fabric may differ from the photos. <Size> Flat dimensions (height x width): Approximately 11cm x approximately 13cm Pocket gusset: Approximately 2cm
