Review on Norpro 411 Silicone Expandable Trivet by Dan Sturm

The coasters can be folded up compactly. They're all plastic, so they seem perfect for the marine environment. Unfortunately, tenants cannot know what they are. Booths must be marked. They also work well under dishes in the fridge. They keep the containers off the glass shelves and allow air to circulate to cool faster. So far I have not tested them on a very hot pan. Boiler temperature works fine. Attached is a picture of silicone coasters marked with a permanent marker.
