Why We Picked It
Ahimsa (Sanskrit for "non-harm") was founded by Dr. Manasa Mantravadi, a board-certified pediatrician, after she realized most kids' dishware on the market carries health risks her patients' families didn't know about. The entire line is 304 18/8 food-grade stainless steel — the same recycled alloy commercial kitchens and medical instruments use — sourced from audited suppliers that provide batch-level mill test certificates documenting full chemical composition. Products are MADE SAFE certified, third-party tested at a US CPSC-certified lab, and have been independently XRF-tested by Lead Safe Mama with non-detect results for lead, cadmium, arsenic, mercury, and antimony. Designed in the USA, manufactured in India.
Same cup as the classic silver version — 8oz, small-hand-sized, rolled lip, no plastic — with the rainbow-and-iridescent PVD finish for families who want some color at the table. Because the PVD is bonded into the metal rather than applied as a coating, it survives the dishwasher indefinitely without fading or chipping.
The colored finish is titanium PVD (physical vapor deposition) — the same medical-implant-grade ceramic bonding technology used on high-end watches and surgical instruments. It is molecularly bonded to the steel, not painted or dyed, so it cannot chip off into food. Free of BPA (and all bisphenols), PVC, phthalates, lead, siloxanes, melamine, and formaldehyde.
How It Fits Our Good Steward Standards
- ✓
No PFAS
Stainless steel is inherently PFAS-free — no non-stick coatings, no plastic, no silicone anywhere in the product. MADE SAFE certification explicitly prohibits PFAS.
- ✓
Toxin & Heavy-Metal Free
Independent XRF testing by Lead Safe Mama confirms non-detect for lead, cadmium, arsenic, mercury, and antimony. Every batch of steel ships with a mill test certificate documenting its chemical composition.
- ✓
Full Transparency
Alloy (304 18/8), finishing process (titanium PVD or hand-polish), manufacturing origin (India), and supplier audit program are all openly published — no proprietary fine print.
- ✓
Minimal Processing
A single-material product: inert stainless steel, with an inert ceramic finish on the colored variants. No composites, laminates, plastics, or silicone components.
- ✓
No Artificial Dyes
The color on rainbow and iridescent variants comes from a titanium ceramic layer vapor-bonded to the metal itself — not from paint, dye, or polymer pigments.
Care & Use
Dishwasher safe on the top rack. To preserve the PVD color finish, avoid abrasive scouring pads and harsh detergents (e.g. citrus-based or chlorine-based pre-rinse cycles). Use wooden or silicone utensils for serving if you want to keep the mirror shine — metal utensils can mark the finish over years of use. Not microwave safe, as with any stainless steel.
