Osinkjet T502-Compatible Ink Refill Bottle Combo Pack, Black and CMY

An auto-stop bottle design helps make refilling compatible EcoTank and WorkForce ink tanks more controlled, while the black, cyan, magenta, and yellow inks cover everyday text and color printing. The combo pack is compatible with a broad range of Epson ET and ST printer models, so it can suit households and workspaces that already use a supported tank printer.

For high-volume printing, the stated yield is up to 43,500 pages at 5% coverage on A4 paper: 24,000 in black and 6,500 in each color. That gives you a practical way to replenish all four ink colors in one purchase rather than sourcing each color separately.

The essentials

This refill ink is designed for compatible Epson EcoTank and WorkForce models, including the ET-2850, ET-3850, ET-3760, ET-4850, ET-15000, ET-2750, ET-2760, ET-2980, ET-2988, ET-3750, ET-3830, ET-4750, and ET-4760, as well as ST-2000, ST-3000, ST-4000, ST-C2100, and ST-C4100. The full listed compatibility also includes ET-2700, ET-3930, ET-3950, ET-4950, ET-3700, ET-3710, ET-3843, ET-3943, ET-3958, and ET-4958. Match your printer’s model to this supported range before filling its tanks.

The pack provides black alongside cyan, magenta, and yellow, with a stated yield of up to 24,000 black pages and 6,500 pages per color. Those figures use 5% coverage on A4 paper, making them a useful reference for planning regular document and color-printing needs. Unlike a cartridge-replacement approach, these bottles are intended for refilling the tanks in compatible EcoTank and Supertank printers.

Who it’s for

This set is suited to owners of a listed tank printer who want black and color refills together. It can be especially practical when printing includes both text-heavy documents and color pages, since the pack covers all four ink colors. For a typical home office, that means the same refill set can support routine paperwork as well as charts, school projects, and other color output, depending on the printer and the document.

Practical tips

Check the model name on your printer against the compatibility list before opening a bottle. When it is time to refill, use the bottle for the matching ink color and follow your printer’s normal tank-filling procedure. The bottles feature an auto-stop design intended to help control filling and reduce spills. Individual packaging also makes it easier to keep each color organized between refills.

Buying verdict

Choose this Osinkjet combo when you need refill ink for a supported Epson ET or ST tank printer and want black, cyan, magenta, and yellow together. Its model-specific compatibility, auto-stop bottle design, and stated high page yield make it a relevant fit for ongoing home or office printing, particularly when both monochrome documents and color pages are part of the routine.
