CUPKIN Insulated Tumbler with Lid and Straw for Adults

Cupkin: The Story Behind the Brand

Welcome! We are Cupkin, a brand that was accidentally created while teaching our two young daughters about grit and determination. From day one, our mission has been to show how a simple idea and hard work can make a real impact on the world around you.

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: Designed with toddlers and big kids in mind, our breathable and flexible bandages provide comfort and protection.

Why We Do What We Do

Our children won't be young forever, so everything we do is focused on strengthening the connection with them before it's too late. Connecting with amazing parents worldwide is what we love most about our work.

What Sets Cupkin Apart

Handcrafted Design: Every Cupkin product is designed by hand, not just a generic label on cheap items.

Manufacturing Excellence: In the early days, we learned from the founder of a leading water bottle brand. Our manufacturing is world-class, and our cups are third-party tested.

Lifetime Guarantee: Any Cupkin product you purchase is covered for life.

Introducing the Original Cupkin Tumblers

Cupkin tumblers are not just another copycat brand. Each set includes two 20oz coffee tumblers (aqua and periwinkle), two lids, and two silicone straws, all with a Children's Product Certificate (CPC test #67122-070011) from an accredited US lab.

It took numerous initial samples to perfect our kids' tumblers, but we're always innovating. We've applied lessons learned from industry leaders to continuously improve our design and construction.

While others may copy our products and colors, our focus will always be on creating items that help parents and children connect.

Cupkin Accessories and Sizes

In addition to our 20oz Mommy/Daddy tumblers, we offer: - 12oz Big Kids Cups - 8oz Toddler Cups - Replacement Lids (2-pack) - Waterproof Sticker Sheets

And don't forget our ever-growing collection of sticker books, with over 500 stickers per book across a variety of themes!

About Cupkin

Cupkin was founded in 2019 in Mill Creek, Washington, by husband-and-wife team Max and Soo Jin. We have no investors, so everything we do is centered around your special bond with your little ones.

What Makes Cupkin Unique?

We were the original brand to create premium stainless steel cups for kids, with 7 human touch points during manufacturing and official Children's Product Certificates.

Our double-wall vacuum insulation keeps drinks cold for 8-12 hours and hot for 4-6 hours, preventing heat transfer through the cup walls.
