A box is shaped around its content; a bowl shapes its content. A box is designed to fit into a space with other boxes; a bowl is awkward and outstanding. The content of a box is padded, sealed; the content of a bowl can breathe. To get to its content a box is irreversibly altered; a bowl is emptied and filled many times over. A box inside a box disappears from view; a bowl inside a bowl is elevated. A box can be flattened without breaking.
You may have something substantial to offer. Are you making bowls, or boxes?
