labels are (or were) £60 a 1000 from print carrier, semi water proof, (very good)
i do my own but to be honest you don't save that much and it is a pain, i think they work out at around 85p all in, (depending on strength of mix) luckily my son sticks the labels on and i fill a few each day to leave with custies. if you've got time or staff sitting around doing nothing then its probably worth it if your giving them away, if however your a one man band, very busy and getting good money for your work, or selling them then you would be better off getting them from restoremate or some other reputable company.
