Thank you for viewing! ♡ Handmade item ♡ I make each item with care, but they are not perfect. Please refrain from purchasing if you are concerned about minor details. Thank you for your understanding. Material: 100% cotton Size: Approximately 11.5 x 19 cm ☆ Suitable for around third grade of elementary school, but there may be individual differences, so please check the size. ⭐️ The vertical center is stitched with two layers to make it less likely to touch your mouth and easier to breathe. ⭐️ Stitches are applied as much as possible to make it durable, which should prevent shape distortion after washing and make it easy to care for.
