Adidas pencil case, color is red ☺︎ Product size: Length: 9 cm Width: 20 cm Depth: 5 cm Retail price: 1,870 yen Please note that there may be some errors due to amateur measurements. My son uses the same one, and it seems to be very easy to use because it has enough space even with a ruler and compass inside ◎ For someone who will use it ☺︎ I will send it via Mercari delivery, so please refrain from price negotiations. When sending, I will flatten it to a thickness of 3 cm, so please be aware of this (*^^*)
