I've come to the end of the road with my current mug supplier. Won't name them, but they are probably one of the largest suppliers in the UK. Quality has been inconsistent for the 18 months I've been using them. Size differences, surface quality differences, chips and bumps, and that's usually in the same box. This evening it took me 7 mugs to get a single acceptable mug due to surface inconsistencies. So, I'd appreciate it if you could give me your recommendations for blank mug suppliers.
