I notice that they take great pains not to mention the minuscule size of these bottles. Just how tiny are they?

Yes, it is VERY hard to find the amount of liquid in different bottles. They often do not state size. Some are 60ml, some 70ml, some 127ml and other sizes. I still like the ink but its very hard to compare price and size.

How much ml came in this bottle..?

Hi dark_drakko, The Epson 502 Cyan, Magenta, Yellow ink bottles contains 70 ml. each while the 502 Black ink bottle has 127 ml. Hope this answers your inquiry. - The Epson Team

Why does the combo pack cost more than individual purchase?

Packaging three bottles in a blister pack

Will this work with the ET-2720 model?

Hi DANIEL ALVAREZ, No. The T502 is not compatible with the Epson ET-2720. Use T522 when you order or purchase new ink bottles. To get good results on your printouts, please use Genuine Epson Ink. Hope this clarifies your inquiry. - The Epson Team
