Like our original straw, the Kiki Kiddo Straw is crafted from 100% medical grade silicon and is composed of two pieces – the mouthpiece and a straight straw that extends into the bottle. This allows kids to drink upright (with the straight straw attached) or by tipping the bottle up (with the straight straw removed). As with all products in the Kiki line, our straw module is 100% plastic-free (unlike many other lines which use plastic components in their straw cups). With Pura, you can be sure you are always using the safest products for your child.
