Our Commitment
At Pottery Barn Kids, we have a firm commitment to safety and quality. We take great pride in our timeless designs, sustainable sourcing, premium materials and expert craftsmanship.
Lead Testing
One of the most important tests for developing infants and children. We require extensive lead testing at both surface and substrate levels to ensure that our products exceed both those levels achieving higher than industry standards in many countries.
Insulated Lunch Boxes and Thermoses for Food Safety
Insulated lunch boxes and thermoses are the preferred option to maintain safe food temperatures until food is ready to eat. Adding an ice pack to our lunch boxes helps prevent perishable foods from spoiling and keeps drinks cold on hot days at the beach.
Reusable Lunch Boxes and Food Containers, Better for You and the Environment
Who wants a boring and wasteful brown paper bag when you can have a personalized lunch box in colorful and glow- in- the- dark patterns? Our utensils, food containers and bento boxes are also designed to easily fit together in our lunch boxes. No more guessing if other food containers will fit in our lunch boxes.
Dishwasher Safe, BPA-Free and Made with FDA-Approved Materials
Everyday items like food storage and thermoses shouldn't be a chore to clean. Most of our lunch and food products are top-rack dishwasher safe or have molded sections that easily wipe clean. Remember that some containers made from metal or melamine cannot go in the microwave, so you will need to transfer the food stored in those to microwave-safe containers first.
Global Safety Standards Acumen
Since quality and safety standards can change from place to place, we aggregate the highest safety standards from the many countries and nations we do business with to holistically develop our own global standards for our many products. Our quality teams attend regular ASTM meetings and conferences to stay ahead of industry trends.
3rd Party CPSC-Nominated Testing Partners
We stand by each product and test in our name for accountability. We use accredited 3rd party labs nominated and regulated by the CPSC (Consumer Product Safety Commission). Our partners test everything in the box, including labels, packaging and materials to ensure product safety compliance.
Your Opinion Matters
We review all returns and take customer feedback very seriously. Many of us at Pottery Barn Kids are parents ourselves and listen to your feedback to make better and safer products for healthier homes.
