Silicone construction solves the perpetual problem of pencil cases that tear, stain, or absorb spills from leaky pens. These flat pouches from Japan's PuniLabo line resist everything that ruins fabric cases, india ink, marker bleed, eraser debris, and wipe clean with a damp cloth. The dual-zipper design lets you open one end for quick access to frequently used tools or unzip both sides to lay the pouch completely flat for full visibility of contents.

Sturdy silicone maintains its shape without going rigid; pouches stay flexible enough to squeeze into packed bags while protecting delicate supplies like technical pens or pastels from crushing. The flat profile slips easily into portfolios or backpack compartments without the bulk of traditional pencil cases. Animal motifs range across the collection, each rendered in PuniLabo's characteristic playful style that makes identifying your supplies in a shared studio space effortless.

Whether you're corralling fountain pens that can't tolerate jostling, separating clean brushes from dirty ones, or organizing small collage materials, these pouches handle storage and transport without the anxiety of wondering if something leaked or broke inside.
