I bought these for my husband and I as we love to go to music festivals in our campervan and wanted to cut down on the plastic consumption. My first attempt to use them was a complete waste of time, as the girl behind the bar poured the drinks into our stainless steel from the 'paper' cups, and promptly put the 'paper' cups in the bin !!!
We had much more success at the Cornbury Music Festival when we used them all weekend. Lots of people in the queue at the bar commented on what a great idea they were. They were used for beer, cider, wine and even gin and tonic. And I'm pleased to say that we used no plastic all weekend :) Looking forward to using them for years to come. And they are made in the UK - BONUS ;)
