The Demon Slayer Mini Backpack by Terrific Planner.

Each 'Demon Slayer' backpack is a unique piece of art. Due to variance in print, no two backpacks are exactly alike. Each is a one of a kind handcrafted piece!

Materials: Fully interfaced recycled canvas complimented by a black colored vinyl that is soft to the touch yet strong enough to hold up to everyday use and abuse. The inside is fully lined in a beautiful coordinating waterproof canvas.
Storage: Plenty of room for all of your daily essentials. Pockets galore: front zipper pocket, inside zipper pocket, and an inside slip pocket.
Fashionable Design: perfect for casual yet nice enough for fun formal wear. The backpack has a grab handle, 39 inch adjustable straps, and closes with dual Nezuko zipper pulls.
