Grosmimi Stainless Steel Kids Tumbler - 10oz (18 Months+)

The tumbler body is named as 304 stainless steel outside and 316 stainless steel inside, an undecorated food-grade metal construction with no bamboo or composite material involved, and it is electropolished without residual polishing compounds.

The food-contact interior is SUS 316 stainless steel rather than a coated surface, but the tumbler's exterior carries printed designs such as Cherry Peach, Unicorn and Dino Khaki, and no lead or heavy-metal testing of that print is published.

The drinking tip is disclosed as silicone and BPA-free, and the body is named 304/316 stainless steel, but no bisphenol (BPS/BPF) or phthalate statement is published for the silicone tip itself, only a bare BPA-free claim.

Care guidance explicitly bars microwave and oven use rather than promoting it, and gives per-part sterilization compatibility along with a concrete 2-3 month silicone-parts replacement interval and scratch-prevention advice using a soft brush.

The care guide gives a concrete replacement interval for silicone parts (every 2-3 months) and explicit sterilization compatibility per component — hot water, UV, dishwasher and steam all specified, with microwave use explicitly excluded rather than marketed.

We queried the complete CPSC recall database directly — 10,027 records spanning 1973 to 2026, with a control confirming the corpus covers comparable product classes like toys and pacifiers — and found no recall filed against this brand in any role.

The brand's NSF-certified, FDA-compliant material claim and a third party's LFGB heavy-metal test citation both attach to PPSU feeding bottles and straw cups, not to this stainless-steel tumbler, whose disclosed materials are SUS 304/316 steel, BPA-free plastic, silicone and TPE with no independent or brand certification named for those materials.

Materials are fully itemized by component (SUS 316/304 body, BPA-free plastic cap and ring, silicone tip, TPE strap), country of manufacture is disclosed as Korea, and the brand publishes a concrete 1-year warranty against manufacturing defects and leaks with no-questions-asked replacement.
