Rectangular Clamshell Sized Precisely for Compact Tumblers

The box is proportioned to cradle short-form vacuum sports bottles horizontally — the molded base cavity hugs the tumbler's cylindrical body with contoured side walls that prevent rolling or lateral shift during transit. The lid closes flush with a clean perimeter edge and a small integrated tab for easy opening. Off-white pulp surface across both panels gives the closed box a minimal, product-forward appearance that works directly as retail-shelf presentation.

Paper Band Wrap Carries Branding Over an Unprinted Shell

A color-printed paper band wraps the closed clamshell horizontally, displaying product name, volume specs, and brand identity without any ink applied to the pulp itself. This unprinted pulp shell with removable band wrap allows the same base clamshell to serve multiple SKUs — swapping only the band for different colorways, capacities, or markets — reducing tooling cost and inventory complexity across a product range.

Pulp Construction Replaces Polystyrene Foam in Tumbler Shipping

Where most insulated tumbler packaging relies on expanded polystyrene or thick corrugated filler, this biodegradable Thermos packaging achieves equivalent protection through precisely molded pulp walls — dense enough to absorb impact, lightweight enough to keep shipping costs down. The entire unit is curbside compostable with no foam to landfill and no plastic film to peel away, making it a direct structural replacement for conventional drinkware packaging formats.
