You know the drill.
You've turned up to the game/film/gig/generic event, anticipation of the evening's entertainment bringing on a strong thirst. However, such is the way of modern venues, a cold can of beer is going to cost almost as much as your ticket in.
If only there were a solution to this quandary (you can see where we're going with this, can't you)?
The unlikely hero of this story is a lid: the Lolo lid. Snap it onto the top of a regular can of beer and you can safely stow the offending beverage in an inconspicuous coffee cup.
One stealthy beer cozy will set you back just £7.92 - though you'll need to find your own medium-to-large coffee cup to affix it to.
And for a scenario we can't quite conjure up in our minds, there's also the Lolo Beer Mat - a yoga mat roll that can smuggle six cold cans into... a yoga class? If you can actually think of a use for it, it's available here for £21.13.
