The Stemless Champagne Glasses each have a capacity of 265ml (9oz) and are a perfect option for outdoor dining or picnics in the park. These stemless ‘glasses’ are not actually made from glass, but from polyethylene terephthalate (PET plastic) which looks like glass when used. Continually reuse your glasses to get their maximum usage. Once you decide it’s time for some new ones, simply place them in the recycling bin. The Shatterproof Stemless Champagne Glasses are BPA free.
