Made in Korea · premium brand since 2004
Korean care for modern parenthood. Since 2004 we have combined modern innovation, quality materials and minimalist design so that our products grow together with the child.
Three technologies
Grosmimi builds every product on the same three foundations — the material it starts from, the way it seals, and how easily it comes clean.
Polyphenylsulfone — a polymer also used in certain medical applications and in aerospace. It is the starting point of every product, not an upgrade.
A layered sealing system rather than a single valve. Each mechanism works on its own; together they hold the cup shut in any position.
Built so there is nowhere for mould to sit. Every surface is visible, reachable and washable without a specialist brush.
Brand story
The founder on why she went looking for a different bottle — and where it led.
The range
Six ranges that follow on from each other. When a child moves to the next stage you change the teat or the straw — not the whole bottle. Parts fit together across the entire range.
200 and 300 ml, with a stage-matched silicone teat.
Soft straw, +Cut anti-leak valve and easy-grip handles.
SUS316 insulation — drinks stay cold for hours.
PPSU or insulated steel, one-touch cap and folding handle.
Three or five compartments, silicone suction base and lid.
Teats, straws, spouts, replacement sets and cleaning brushes.
Published research
Two findings — one from our own product test, one from a published study of the material. We cite exactly what they report.
No microplastic particles larger than 45 μm were detected in a sample of the Grosmimi PPSU feeding bottle. One sample was tested, using the laboratory's in-house method.
KOTITI Testing & Research Institute, report no. 8224500100261, 2024A 2018 study of non-intentionally added substances (NIAS) in PPSU baby bottles found no exceedance of the specific migration limits or toxicological thresholds of concern assessed under the test conditions. The study concerned PPSU materials and was not a test of Grosmimi products.
NIAS assessment, PubMed, 2018The first finding concerns one tested sample of the feeding bottle; the second concerns the PPSU material as reported in the cited study. Neither is a claim about the whole range, nor a promise of a specific result in your home.
One bottle, five uses
Questions parents ask
PPSU (polyphenylsulfone) is a high-performance polymer also used in certain medical applications and in aerospace. It withstands 200 °C, so it survives repeated boiling and steam sterilisation without warping or clouding, and no BPA was detected in the components tested.
Boiling, steam and UV sterilisation are all fine. PPSU is rated to 200 °C, the silicone parts to 180 °C. Take the product apart first so water reaches every surface, and let the silicone parts dry fully.
Feeding bottles from birth, with teat stages 0 to 4 as the flow needs to increase. Straw cups 200 ml from around 6 months, 300 ml from around 12 months. Tumblers and food trays from roughly two years, when a child drinks and eats unaided.
PureSeal™ combines a cross-cut silicone straw that blocks backflow with an air valve that equalises pressure inside the cup. Each part works on its own, and together they keep the cup closed when it is tipped, shaken or lying in a bag. As with any cup, the seal depends on the parts being assembled correctly and the silicone being in good condition.
That is what CleanCore™ is about: fewer than five parts, an opening wider than 40 mm, and full disassembly with no hidden crevices. Narrow straws need the dedicated brush — it is the one part a sponge cannot reach.
