The Ultimate Stainless Steel Sippy Cup: How it Works

You can confidently hand any beverage to your child without worry. Once you stretch on a lid, even if the cup is shaken violently or tossed across the room, it remains leak-proof!

Cups and lids are dishwasher-safe.

Flexible and durable, the silicone lids are easy to apply and remove from your cup. To apply:

  1. Grab the bottom of the sippy lids and stretch outward.
  2. Use the backs of your hands to keep the cup steady as you pull the lid down.
