Thousands of Happy Customers!
Love, love, love these bowls! Perfect size for my grandkids, and I use them for multiple uses myself! They are stainless steel (replacing plastic bowls for the kids) and the silicone sleeves make them slip resistant, and easy for the kids to hold on to the bowls. They are easy to clean, and do not hold a smell from previous food they held. Good price for a great product!

Wish I had bought these years ago! They are sturdy, and love that I can put them in the dishwasher. I was worried that water may get under the silicone cover but no issues after a few months.

Great size and clean easily! These have been a great size for our toddlers and the stainless steel is easy to clean. I also like how well the silicone sleeve stays on and it’s a great color just like pictured. They definitely seem durable even after a few drops we haven’t noticed any dents.
