Stoneware Canister with Airtight Lid | "Iwa" 岩

A set of three stoneware-style canisters with fitted lids, designed for practical storage and sealed with a flexible TPU ring.

Set Composition

• Three sizes: small, medium, and large.

Lids

• Each lid contains an inner recessed ring.
• The recess holds a custom TPU band that stretches around the lid and settles into place.

Seal

• When the lid is pressed into the canister, the TPU ring compresses against the inner wall.
• This creates an air-tight seal that secures contents and preserves freshness.

Food-Safe

• Food safety depends on print material and post-processing.
• A stainless steel or dedicated “food-safe” nozzle is recommended to prevent contamination from prior prints.
• A food-safe epoxy or resin coating can be applied to the inner walls for a non-porous, washable surface.
• TPU sealing rings should be printed with a food-grade filament if intended for direct contact.
