A reusable box includes a bottom, side walls, a lid, a sealing element on the lid to seal the box, and a temporary closure structure on the lid inboard of sides of the lid. The temporary closure structure includes a tab with a folding line to temporarily close the lid. The tab is hinged along the folding line to enable insertion into a slot on a surface of the reusable box in a temporarily closed configuration. The slot has a narrow portion defined by a projection of the surface of the box into the slot, with an opening along the fold line positioned along the narrow portion of the slot in the temporarily closed configuration. The sealing element is located between a free side of the lid and the temporary closure structure such that the reusable box is temporarily closable before and after sealing the reusable box.
