Klean Kanteen Kid's Cup with Straw Lid

Name: Klean Kanteen Kid's Cup with Straw Lid
Brand: Klean Kanteen

Recommended

Recycled-steel cup with a stainless steel straw and silicone lid/flex-tip - no plastic in the drink path, unlike the older PP sippy cap.

The verdict: Silicone only

The 10oz Kid's Cup is 90% post-consumer recycled 18/8 stainless steel, and the matching straw is stainless steel too, topped with a soft silicone flex tip. The Straw Lid itself is food-grade silicone. So with the straw lid, the entire drink path is steel + silicone - no plastic. Note the OTHER lid you can buy for this cup, the Classic Sippy Cap, is polypropylene; pick the silicone straw lid (or the silicone Sippy Lid) to keep it silicone-only.

Lead safety: Tested lead-free

Lead Safe Mama's independent XRF testing has consistently found Klean Kanteen's non-insulated (single-wall) stainless products lead-free. This Kid's Cup is single-wall, non-insulated steel, so it falls in the construction category covered by that testing rather than the double-wall insulated line (where a lead-solder sealing dot under the base is a known risk for other brands). The silicone lid/flex tip and the polypropylene Classic Sippy Cap alternate were not specifically tested.

Verification: Independently lab-tested
