Our new patent pending silicone sealing disks allow all bottles in our Kiki line to be re-purposed as drinking bottles for older kids, as handy food containers in a lunchbox, or as mother's milk storage vessels. These disks sell three to a pack in orange, green, and blue so you can colour code your bottles! As with all of our other silicone products, the disks are crafted from medical grade silicone and and are 100% bpa-free and 100% toxin-free.
