These six Dulce Cocina Bamboo Coasters arrive in a handy holder. They are attractive and inviting to use. I prefer bamboo when possible for its sustainability. The look is quite cool. If you are one who likes large drinks, these are an ample size for even a huge thermos. My favorite use for them is to set under my bamboo essential oil diffusers. They protect my tables from leaks and spills with their ample grooves and look stellar, being bamboo as well.
The disks, being bamboo, are lightweight. They are also slippery. They could slide off a table. The surface makes me overly concerned with the way I set a glass down, lest it tips over.
