Handmade Resin Cartridge Coasters Approximately 10cm diameter, 1cm depth. The coasters are all handmade to order so may contain slight air bubbles in the resin. All cartridges have been recycled from local shoots so may have slight marks on the brass. As they are set in resin they may move in the process of curing so may not sit exactly symmetrical due to this process. Each cartridge is melted off the plastic individually by hand so some may have remained of the plastic on the underside of the coaster inside the metal, this can not be avoided. Each coaster may vary slightly, I will do my best to match cartridges but due to stocks I can not guarantee all matching cartridges in each coaster.
