Review on UMOKOON Packs Premium Silicone Trivet by Joel Miranda

There seem to be two types of these silicone coasters - thicker ones with a vertical edge and slightly thinner ones with a rounded edge. This is a slightly thinner version with rounded edges. There is a slight trace of mold along the edge, but there are no burrs or missing design elements on the inside. There is a chemical smell that will hopefully dissipate over time. 4.5 stars.
