FITS ALL PURA BOTTLES: Pura’s straw top helps little ones make the transition from sippy to a ‘big kids’ bottle. This top easily interchanges with all other Pura tops by simply swapping the Silicone Straw with another Pura silicone lid; extending the usable life of Pura bottles to older kids! 100% PLASTIC FREE: From the bottles to the lids, all of our products are 100% plastic-free. With Pura, you can be sure you are getting the safest, BPA/BPS-free, and MadeSafe Certified products on the market. PREVENT SPILLS:The valveless design consists of two pieces – the mouthpiece and a straight straw that extends into the bottle. This versatile top can be used with or without the internal tube. The added internal sip guard makes it more spill- and toddler-proof. DISHWASHER SAFE & EASY TO CLEAN: Just pop our straws in the dishwasher or sterilize by boiling in a pan for 3-5 minutes. MADE SAFE CERTIFIED: Non-BPA, non-BPS, non-EA, non-PP, non-Polypropylene, non-phthalate and will not leach toxins. Straws are recommended for ages 6 months and up. This advanced design offers a fast flow rate, but allows kiddos to turn their bottle upside down without spilling a drop. Crafted from 100% medical grade silicone and composed of two pieces – the mouthpiece and a straight straw that extends into the bottle — the Kiki 6M+ Kiddo straw 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, it 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.
