I have two sets of custom Star Wars coasters for sale. These are new, never used. 4 1/8" outer diameter, 3/8" tall. They were CNC machined out of 6061 aluminum and engraved with the images you see. Engravings are .01-.015" deep depending on the design. Cork has been glued onto the back of each coaster. A set of coasters is 9 pieces and includes: Star Wars, Imperial cog, rebel symbol, Tie Fighter, X-Wing, Millennium Falcon, Boba Fett, R2D2, and Darth Vader.
The machining marks can be buffed out if you wish. I like them so I left them on all the coasters. The surfaces are perfectly smooth except for the engravings, there aren't weird spiral ridges or anything of that nature.
These were made as gifts and I had extra stock so I ran two extra sets. I will not be making any more, please don't ask.
Price: $120 including shipping.
