OKI C5850n / C5850dn refill bottle and chip

State-of-the-art toner for the OKI C5850n / C5850dn. Comes with the indispensable chip needed to make the machine accept your refilled cartridge and our "no mess" spout.

You'll probably need one of these if you've already done your first refill of this cartridge using our OKI C5850n / C5850dn Starter Kit: and now you want to refill again.
