Hi there, I am looking for a supplier in the UK for mugs that I can use with the laser etcher, any ideas?
It depends on the mug material. If the mug is stainless steel, there are plenty of suppliers that offer plain merchandise for you to add your company logo to - Vistaprint, for example.
However, I would not recommend using ceramic mugs unless you have an enclosure, or first without testing a similar product (bathroom tiles might be best) to check the engraving settings.
