The Sip-Tip valve helps straws to stay full of fluid, reducing the amount of air ingested and effort required. The one-way valve can be trimmed at designated areas, giving the user selective flow restriction. The valve and lid are compatible with most brands of disposable flex straws. The 8 ounce spill resistant tumbler has a graduated scale to monitor intake.
