Keyboard size: 17.5 x 20.5 cm No keyboard size: 17 x 21.5 cm Cup holder: 15 x 16.5 cm Will be folded and shipped. I make these with care, but there may be some imperfections like uneven stitching. I haven't used edge stitching on the seams. These are recommended for those who don't mind if the sewing isn't perfect. How about for preparing for entering school? #Recommended for those who are not good at handmade school entrance preparation sets I also sell lunch bags, chopstick and spoon cases, masks, etc. Please note that the drawstring bags come in various sizes. If you purchase multiple items, please comment. I will offer a small discount.
