When pouring your next cocktail for your guests why not personalise it with some colour and make the glass stand out. Glass markers are an excellent way to identify your drink and a party or social gathering. Just attach to the rim of your glass and press button to activate the three different light sequences that include flicker, flashing or a solid light. The plastic markers are made from food safe BPA free plastic. The markers are reusable but the batteries non-removable and will give approximately 24 hours of light. A great cocktail accessory or gift idea for someone who likes to host cocktail parties.
