This is a case for a laptop. I purchased it on Rakuten for about 54,000 yen. It has pockets and plenty of storage space. You can put things like a power adapter and mouse in the side pockets. I no longer use it and have mostly kept it in storage, so I'd like to pass it on to someone who can use it. Size (approximate): Height: 26 cm Width: 36 cm Depth: 3 cm
