Empty Refillable Cartridges for Epson WF-7710, 7720, 7610, 7620, 7110, 7210, 3640, 3620 | Cosmos Ink®

Welcome to Caps On Fire / Cosmos Ink. First off, I want to say thank you for showing interest in our "Sublimation Ink Conversion Kit." I highly appreciate it and would like to express my gratitude.  

So........you've been doing your research and have came to realize that using refillable cartridges will save a TON of money on ink. This is ABSOLUTELY TRUE!! OEM "original equipment manufacturer" cartridges can get VERY costly due one time use. So instead of spending $45-$50 each time your cartridges run empty, you would simply buy a refillable cartridge and only buy the individual bottles of ink when needed. So whether its sublimation ink, pigment ink, dye ink, or food coloring, you can use our refillable cartridges providing your printer is compatible with our cartridges. For compatibility with these cartridges, please see our compatibility chart below.
