The security tag, on trial at Jaguar Shoes in London’s Shoreditch, is designed to explode with ink when the glass is taken more than 100 feet from the bar.
The innovative security tags incorporate a bespoke ink-exploding device, set off when the tag strays too far from a sensor on the bar door. The ink is cheekily designed to match with Kopparberg’s new Cloudberry and Elderflower & Lime varieties.
Conversation surrounding the glasses on social media first alerted the company to the ‘stealability’ of its new glasses, with some fans even posting pictures of the Kopparberg glass being used as a stylish vase, a desk tidy and a candle holder in their homes.
In an attempt to further satisfy demand for the glass, Kopparberg will also be giving one away each day this week to the fan who suggests the most creative use for it on Twitter, using the hashtag #hideandkeep.
Ideas already include using the glass for a ‘science beaker’, a ‘fishbowl’ and an ‘ice cream sundae’.
Kopparberg head of marketing, Rob Calder, said: “The security tags are obviously a bit of fun, but hopefully they’ll also help bars keep hold of their Kopparberg glassware reserves so that customers can enjoy the Swedish cider experience properly.”
