Fast delivery as always. The only problem at the opening of the carton, there were no references 4 sets of 5 cartridges, but 4 sets of 4 cartridges references: the reference C-526 BLACK was missing, and we had 8 times the reference C- 526 CYAN. So I had to make a return. It is a pity that the seller (COLOUR DIRECT) does not pay more attention to the time of packaging of the order.
