CUPKIN Stainless Steel Insulated Tumbler for Adults

Cupkin - The Brand Behind the Tumblers Cupkin was accidentally created while we, the founders Max and Soo Jin, were teaching our two young daughters about the power of hard work and perseverance. From day one, our mission has been to show our girls that a simple idea, combined with relentless effort, can have a meaningful impact on the world around them.

Our Top Sellers Cupkin Sticker Books: Our innovative sticker books with spiral binding are perfect for young adventurers aged 4-8 who love to explore new places. Cupkin Bandages: Breathable and flexible, these bandages are specially designed for toddlers and big kids.

The Problem We're Solving One day, our children will grow up, and the precious time we have with them as they are now will be gone forever. Everything we do at Cupkin is centered around strengthening the connection between parents and their kids before it's too late.

Why We Love What We Do Connecting with amazing parents from all over the world and supporting them in their journey is what truly drives us. We are passionate about creating products that bring families closer together.

What Makes Our Products Unique Every single item we make is designed by hand - we don't simply slap a label on cheap, mass-produced goods. In the early days, we had the privilege of learning from the founder of the world's most popular water bottle brand, and our manufacturing process is truly world-class. Additionally, any Cupkin product you purchase is covered for life. We stand behind the quality and durability of our creations.

Meet the Original Cupkin Tumblers Cupkin tumblers are not just another copycat brand. These premium stainless steel cups with lids and straws were designed specifically with parents and their children in mind. Each set comes with two 20oz coffee tumblers (one blue, one green), two lids, and two silicone straws. These products have been rigorously tested and certified by an accredited US laboratory, meeting all safety standards set by the Consumer Product Safety Commission.

Cupkin's Innovative Features Our tumblers feature a unique, multifunctional lid that can be used for both hot and cold beverages. The built-in tab allows for safe sipping, while the straw hole and vent keep spills at bay. Cupkin cups are also designed with a durable, powder-coated finish that prevents chipping and peeling, unlike enamel-painted reusable bottles.

Where is Cupkin Based? Cupkin was founded by Max and Soo Jin in Mill Creek, Washington, at the end of 2019. The team is spread across the country, and the company has no investors - everything we do is focused on strengthening the special bond between parents and their kids.

Cupkin vs. the Competition Cupkin was the original brand to create premium, stainless steel cups designed specifically for children. Our manufacturing process involves 7 human touch points, and all our products are officially certified by the US CPSC. While competitors may try to copy our designs, our unwavering focus will always be on you and your family.
