These straws have one-way valves which stay filled with fluid even after removing the straw from a user’s lips. This feature eliminates the possibility of sucking in too much air while drinking. The clip-on straw hooks onto the side of a glass or cup to prevent the straw from falling out.

Each pack includes:

• One x 255mm (10″) straw
• One x 178mm (7″) straw
• Both straws have a 6mm (1/4″) diameter hole
