When I used to take naps during class, I couldn’t rest my head on my arm because I’d lose circulation pretty quickly. So I’d pull out a looseleaf paper and sleep with my head directly on the desk. Mad uncomfortable. This right here would’ve been so clutch. Power (up) naps and all that.
I’m not really sure how much it costs because I can’t understand Japanese (I can read it though! …). But you can pick it up from E-capcom.
