These Titanium Drink Coasters are minimal, elegant, strong and most importantly functional. The glass bead finish helps in avoiding condensation from causing your glass to stick to the coaster. Glass beading also leaves a smooth matte finish that complements all types of different drinkware. They have also used a special non-slip neoprene base on the bottom to prevent your coaster from sliding around. They’re tough, durable and made for everyday use. Whether at home, in the office or your workshop, these Titanium Coasters are built to keep your surfaces safe while looking like they always belonged there. Being made from Titanium means they won’t shatter, rust, dull or change their beautiful appearance for as long as you own them! The coaster is 3.50″ in diameter and is made from 0.100″ thick solid Grade 5 Titanium. It serves its purpose and is thick enough to be sturdy and stable, but still sleek and easy to store and does not take up valuable desk real estate.
