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 x 90 mm. 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.
