Price is for one straw topper. Our silicone straw toppers come in different styles.  Toppers fit most 10mm resuable straws and are made of BPS-free silicone.  Fits straws for most 30-40 oz. cups/tumblers including Stanley and other brands.  Please verify your straw size before purchasing! There is a hole at the bottom of the topper, the hole does not go all the way through the top giving this a nice snug cap fit to your straw. Customize your topper by adding charms or add to your own custom items for a great tumbler gift set!
