About Cupkin
A plastic sippy cup that stains, cracks, and eventually gets tossed isn't really built for a toddler who'll use it daily for years — Cupkin builds theirs to actually last that long. Cupkin is the original brand behind premium stainless steel cups for kids, founded by a husband-and-wife team in Washington State, offering stackable, powder-coated 8oz and 12oz insulated tumblers with BPA-free lids and silicone straws.
Every cup uses food-grade 18/8 stainless steel and goes through 7 manual touch points during manufacturing, backed by official Children's Product Certificates through the U.S. CPSC. The vacuum-insulated double wall keeps drinks cold for 8-12 hours or hot for 4-6, and the powder coating resists the chipping and peeling that plagues painted metal alternatives. It's worth noting Cupkin issued a voluntary recall in 2023 related to lead levels in certain tumbler models — the company has since maintained an ongoing focus on safety testing, but parents may want to confirm the current model they're buying reflects post-recall specifications. Every cup carries a lifetime guarantee against manufacturing defects when registered. For parents who've gone through one too many cracked or stained plastic cups, that combination of real durability and CPSC certification is the whole draw. Before ordering, it's worth checking this page for the current Cupkin discount code or coupon code — seasonal promos can meaningfully cut the final price.
💰 Available Coupons & Discounts
Codes for Cupkin tend to move fast, so it helps to check this page before checkout rather than relying on memory. Beyond the standard Coupon Code, keep an eye out for a rotating Promo Code, bundle Deals, seasonal Discounts, and occasional flash Sales.
💡 Shopping Tips
🧼 Hand wash rather than dishwash the cup body to keep the powder-coat color vibrant longer.
