This is an aviation kneeboard suitable for using an iPad mini in an aircraft cockpit. It's versatile enough to be used anywhere, not just in an aircraft. It's a bi-fold type with padding, and also has a clipboard and pockets. I purchased it through personal import from Sporty's, a U.S. aviation supply shop, but I made a mistake in the size as my iPad is an Air, not a mini. The list price was $29.95, with shipping at $24.18, for a total of $54.13, which was about ¥8200 in Japanese yen. I purchased it in August and have not opened or used it.
