vinolid holds aroma in the glass while keeping insects and other debris out. While it looks and feels like glass, it’s actually made from a food safe, BPA-free polymer which is shatterproof, dishwasher safe, reusable, recyclable and made in the USA. vinolid measures 3.5” in diameter so it fits most wine or other glasses, even many decanters! This package includes two vinolids in a custom linen bag, with logo and drawstring that keeps your lids clean and allows you to slip a vinolid into your purse or pocket for use on the go.
