We spoke to a customer this morning that bought cork back coasters from us 10 years ago and they are still being used.  However much they were (considerably more than they cost now); after 10 years you have to admit that this is really good value for money.  Now we know they last that long maybe we should charge more!  The cork back coasters are made from gloss laminated print + greyboard + obviously the cork.  We can produce them in 2 thicknesses either 1500 micron or 3000 micron.  We can categorically state these are very durable, long lasting and good value for money The greyboard used in these is recycled.
