This is an A4-size tablet case that fits in a randoseru (Japanese school backpack). It perfectly fits the Chromebook used in elementary school. There is a pocket on the front, so you can put supplies there. Outer dimensions: Length 32.5cm Width 24cm Depth 4cm Urethane sponge is sandwiched between the main body and the sides. Adhesive interlining is applied to the outer fabric and side fabric. The lining uses quilting, which can prevent scratches on the surface of the tablet, but it does not have enough cushioning to protect the performance of precision instruments, so please understand. This is a handmade item by an amateur, so there may be some misalignment of seams and distortion of stitches. Please purchase if you understand. m(_ _)m It will be shipped via Rakuraku Mercari delivery. Tablet case Chromebook case Handmade Liberty
