No longer will you have to spend a fortune each time you run out of ink. Nor will you have to throw away a costly and perfectly usable print head when just a single color is empty. Simply pop the top off the genuine cartridge, remove the ink sponge then insert the Pop Cart refill. The Pop Cart insert contains twice the ink of a genuine cartridge and when it's empty, you simply replace it with another pop cart insert again and again.
