Inkedibles edible inks are FDA compliant food inks designed to work with inkjet printing technology, and are intended to be used only in brand new compatible Inkedibles refillable ink cartridges that are filled only with Inkedibles edible ink. Never use edible ink with a cartridge or printer that has had regular ink running through it because contamination can occur. Be careful not to order a regular ink cartridge for use with edible printing! Only the items shown in the INKEDIBLES section or described as such, are intended for food decoration purposes. Note: Some printers that utilize the cartridges in this multipack also use an extra cartridge called CLI-251 Gray. This is not common for most printers used for edible printing, but you should check to see if your printer also needs this Gray cartridge (such as the PIXMA iP7250, iP8720, iP8750, MG5450, MG6320, MG6350, MG7120, MG7150 printers), if so, the gray edible ink cartridge is sold separately by Inkedibles (not part of this multi-pack).
