Oh, England. From inventor James Nash comes these single-serve plastic wine glasses with a tear-off lid with either Shiraz, Rose, or Chardonnay. And at £2.25 (or $3.30), British retailer Marks & Spencer can't keep them in stock, the Daily Mail reports. The funny backstory is that Nash was on the BBC reality show Dragons' Den (the UK equivalent of Shark Tank) and the investors "gave him a torrid grilling and bowed out because they were unconvinced anyone would be interested." Apparently, the M&S Le Froglet wine individual glasses are popular with those about to engage in an "impromptu picnic" and with "commuters who want to enjoy a drink on the train home from work."
