Stainless Steel Collection

Upgrade from plastic with Grosmimi's stainless steel collection. Double-wall vacuum insulated cups keep drinks cool for up to 6 hours. Made with premium 304/316 stainless steel, these cups are non-toxic, durable, and dishwasher safe.

Choose from straw cups with flip-top lids for toddlers and insulated tumblers for older kids. No plastic ever touches the drink. Korean-made quality that lasts.
