I have purchased many items including CIS systems for my 3 printers which came with very clear instructions and work excellent.

I have also purchased normal ink and sublimation ink for many years and have never had any problems, I buy all my sublimation paper from CityInkExpress, as I find it excellent quality.

If at any time I have had a problem someone has always answered my query.

Thanks CityInkExpress for your service.
