It’ll be al-light on the night with a little help from Wowcher… Today we’re offering you a set of 4 LED coasters for £6.99, or 8 coasters for £11.99, saving you up to 65% off Groundlevel’s prices (correct as of 20.11.14). Get groovy with your gin and marvel at your mojitos with these amazing coasters that light up and change colour regularly. Each coaster measures approximately 3.5" wide to fit most glasses, and they creates a mesmeric light-show effect when placed underneath clear glasses. We reckon they’ll make a great talking point at festive parties!
