Knockoff Stanley Tumblers for Children Recalled Over Lead Toxicity

Updated: Jul. 25, 2023

These affected tumblers are specifically designed for children, who are most susceptible to developmental issues from lead poisoning.

The Stanley Quencher Tumbler has taken the consumer market by storm. With Magnolia-branded versions and custom cups personalized with script, Stanley’s popularity is evidently soaring. It’s no surprise, then, that knockoff Stanley tumblers have also been developed by various companies, such as CUPKIN’s stainless-steel versions. Unfortunately, not all of these knockoffs are safe to use, with the US Consumer Safety Product Commission (USCSPC) demanding a recall on specific CUPKIN tumblers on July 20, 2023.

Here’s everything you need to know about the CUPKIN tumbler recall, including which products are recalled, why they are being recalled and what you can do if you own a recalled tumbler.

Which Products Are Being Recalled

According to a statement on the USCSPC website, the recall specifically targets “improperly manufactured¬†8 oz. and 12 oz. models of CUPKIN Double-Walled Stainless Steel Children’s Cups.” The cups come in pairs, with each cup featuring a printed “cupkin” logo at the front bottom of the cup and a matching straw. Both sizes of cups were sold in 12 different colorways, outlined below:

  • Blue and green
  • Pink and purple
  • Blue and gray
  • Peach and teal
  • Black and white
  • Coral and yellow
  • Green and pink
  • Polignac and potpourri
  • Brown and peach
  • Rust and salmon
  • Aqua and periwinkle
  • Cobalt and mint

The defective tumblers were sold on and from January 2018 to March 2023, and cost about $20.

Approximately 346,000 units are being recalled by Soojimus (doing business as CUPKIN) due to lead contamination. In the words of the USCSPC: “The stainless-steel cups contain levels of lead that exceed the federal lead content ban. Lead is toxic if ingested by young children and can cause adverse health effects.”

According to the World Health Organization (WHO), lead poisoning can lead to issues in the development of the brain and nervous system in children. In adults, lead poisoning can increase the risk of high blood pressure and kidney damage, as well as of miscarriage, stillbirth and premature birth in pregnant individuals.

What to Do if You Have a Recalled CUPKIN Tumbler

First, stop using the tumblers immediately and take them away from any children using them. Then, contact Soojimus for a full refund. To do so, you can call them at 888-721-0096 Monday through Friday from 10 a.m. to 2 p.m. PST. You can also email the company at [email protected] or submit the recall form through the Cupkin website here. Note that Soojimus and Amazon are also reaching out to all known purchasers of the infected cups directly.

If you want a new tumbler in the meantime, you could always look at Stanley’s Outside In collection or the HydroFlask All-Around Travel Tumbler. And if you live in an older house, remember to properly check it for lead poisoning. Stay safe out there!
