These were ones Ian and I had made up before the FWC show, they are 24" long and 10" high, these are also NOT the cheap 'V??ta Print' ones that scratch and peel as these have a clear-coat top layer (as used by taxis etc) to give them a longer life, good strong magnet so wont slide/come off. Not cheap, but then again quality doesnt come cheap, as we paid £40 a pair from a friend of ours but they are a quality piece of kit.
If you want some then let me know, but the P and P may be a bit pricey as they are heavy but maybe able to meet up or take to Windex in March!
