We've designed drink coasters modeled after bicycle cranks to replace the drab coasters found in every household. It's true that we're in the 21st century and technology is advancing at an astonishing rate, but condensation dripping from sweaty drinks will always be the Achilles heel of water-absorbent furniture. Each coaster is made of unbreakable solid steel (16 gauge cold-rolled steel, to be exact) and will be powder-coated in various colors. They're 4" wide and protected by a non-slip rubber bottom. The rubber also protrudes through the crank openings to securely keep your beverage in place.
