Relatively new on the market is the neoprene coaster -- a natural extension from the now ubiquitous neoprene mousepad. Flexible, slip-resistant and durable, neoprene coasters also are washable. 
 
Hardboard Coasters are a staple of personalized products. Even more so with the huge number of digital image files that are produced worldwide. They fit so many market channels that it's tough to think of one that they don't work well in. They are fun to sell because everyone wants a Personalized Coaster and all are extremely durable.
