Grosmimi Stainless Steel Straw Cup with Flip Top - 10oz (12 Months+)

The bottle body is named as an outer layer of 304 stainless steel with an inner layer of 316 stainless steel, both inert, fully food-grade steel grades disclosed directly on the product listing.

The cup's food-contact parts are disclosed as BPA/BPS/BPF-free, going beyond a bare BPA-free claim, and the straw is named as platinum silicone, though no migration test result or method is published for the finished cup.

The cup body is stainless steel rather than painted glass, so the lead-in-paint vector this criterion targets mostly does not apply, but no lead testing is published for the exterior coating or color finishes on the steel body.

The brand tells parents to replace the silicone straw every 2-3 months and to inspect it for damage before each use, but the cup itself is explicitly marked not microwave-safe with no separate guidance on steel-body degradation signals.

The straw is named as platinum silicone, described elsewhere as medical-grade material, but no biocompatibility standard, nitrosamine result, or siloxane test is published for this specific component.

We queried the complete CPSC recall database (10,027 records, 1973-2026) for this brand and found no recall at any date, in any role. The corpus's coverage of comparable product classes confirms this is a clean result, not a missed search.

The brand publishes a concrete replacement interval, telling parents to replace the silicone straw every 2-3 months and to inspect it before each use, discarding at the first sign of damage or weakness.

The straw material is said to be tested to LFGB limits for lead, mercury, cadmium and hexavalent chromium, but that covers one component, and no certificate number, lab name or registry entry is published for the finished cup.

Manufacturing is disclosed as designed and made in Korea with consistent batch tolerances across markets, and the brand publishes a concrete 1-year warranty against manufacturing defects with no-questions-asked replacement for leaks or material degradation.
