YummyInks premium brand edible inks FDA compliant and the best quality inks for your cake and edible ink requirements producing beautiful prints for cake decorators and bakeries. Print with Inkedible Inks for Incredible Cakes! IMPORTANT: DO NOT MIX regular inks with edible inks. YummyInks edible inks (food coloring) are intended to be used only in brand new compatible YummyInks refillable ink cartridges that are filled only with YummyInks edible ink. Never put edible ink inside a cartridge (or inside a 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 YummyInks 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 (not part of this multi-pack).
