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 a single color is empty. Simply pop the top off the genuine cartridge, remove the ink sponge and insert the Pop Cart refill. The Pop Cart refill contains twice the ink of a genuine cartridge and when it's empty, you simply replace it with another pop cart refill again and again. You save time, the environment, and most importantly money! PLEASE NOTE: To use this product you will require a working cartridge. The pop cart refills are inserted into empty genuine cartridges. Once empty, you simply remove the pop cart and replace it with a new refill.
