Presenting a backpack based on an original design by "Keep Your Hands off Eizouken!" author and illustrator Sumito Owara!

The design revealed on Sumito Owara's Twitter account in 2017 has been brought to life under the guidance of Sumito Owara himself!

The outer shell of the backpack looks like real cardboard, but is actually made with durable, water resistant Tyvek® material.

The backpack features a large drink holder side pocket as well as a velcro zone where the shipping label on a typical box would be that can be used to display embroidered patches.

It is also possible to place stickers on the backpack as well as draw on it, allowing you to customize your backpack into a one-of-a-kind creation. Caution tape, orange tape and green tape enamel straps are included for further customizing your backpack.
