These are brand new, high quality, blank, clear acrylic coasters. Each coaster comes in 2 parts, a large base and a cover, into which you insert logos, pictures or artwork. The coaster can accommodate insert size up to 90 mm diameter. Just cut out the insert to the correct size, put it in the base and snap the cover shut to give a finished product. All coasters are individually bagged to avoid scratches. Pictures shown in inserts are for demonstration purposes only and are not included in the offer.
