CLI-42BK BLACK NEGRO NOIR 400ml BOTTLE Clogging proof refilling OCP ink for Canon Pixma PRO-100 (400ml x 1 in HTPE bottle) ENGLISH: this is the best anti-clogging ink to refill CLI-42 cartridges (Canon Pixma PRO-100, for instance). This is expensive but the best around. Forget about low quality China-made inks. You can trust me about the quality and brand, as I use them personally in all my printings, and I had to revert to OCP because I used "good inks" that clogged my printing head (two of them, BTW). You are bidding for one 400ml bottle presented in opaque HTPE bottle (I do NOT use PET bottles, which leach antimony continually and have 4x moisture interchange with enviroment compared with HTPE), good for around 27x refillings (600 worth original cartridges replacement). Remember you have to rinse through original cartridges before refilling them (absolutely DO NOT refill without FIRST flushing throughly your cartridges. Do not mix inks!!). This is exactly what you will receive: OCP Code BK 159 ---- 400ml Canon CLI-42BK (Black)
