Most coasters suffer from a similar issue: they stick to the bottom of glasses, resulting in them being frustratingly dropped on the ground, spilling their contents along the way. After searching for a solution to this issue, I decided to design my own. These coasters utilize thin points of contact with your drinks to ensure there is no sticking due to surface tension. Not only that, but the deeper recesses allow the coasters to hold more liquid that may drip down the side of your glasses, protecting your table. The coasters also fit into one-another, allowing them to be stacked up without a separate holder.
