ゲームボーイ本体用スリーブ - FunnyPlaying

Finally, a sleeve that actually fits my GBA without flopping around — the 16cm x 10.5cm exterior is spot on for tossing in a bag. The little logo on the front is a nice touch, too, makes it feel less generic.

The interior is perfectly snug for my GBA, no rattling at all. The 16cm length is just right to slip into my bag without being bulky.

My old GBA finally has a proper home instead of rattling around in my bag. The sleeve is slim enough to slip into a pocket but still gives the console solid protection, and that little logo on the front is a nice touch.
