We were contacted by a company who had a client that required a small number of keyrings howev er they had to be a particular shape and be printed on both sides. They were not sure of what material to use and how to go about getting their design printed on both sides.
We suggested that we laser cut the keyrings out of 3mm high density mdf and then print both sides using our UV printer.

Both our customer and their client were delighted with the end result.
