The design of this glass sip'n straw cup is outstanding. The temperered glass on the inside is protected all around by a polypropylene plastic shield that protects the glass inside. The Green Sprouts Sip'n Straw cup can be used with the provided silicone sip spout (great for ages 6-12 months) or can be used as a kids glass straw cup (great for ages 6 months plus).
The liquids in the cup only touch glass and silicone. The outer plastic protective cover does not come in contact with the liquids inside the cup.
