The BOROUX™ Stainless Steel Cups come as a set of 4 pint cups, 16 fl oz each, in AISI 304 food-grade stainless steel. Nothing coated, no plastic anywhere. They stack flat in a cabinet, they won't shatter on a concrete patio, and they go from the porch to the cooler to a kid's hands without you thinking about it. Dishwasher safe, and they don't hold onto the smell of whatever was in them last.
