(512,19 PLN netto) Free Delivery | | Description Compatible Ink Cartridge LC-421 BK for Brother (LC421BK) (Black) is a reliable way to keep your Brother inkjet printer ready for everyday work—from crisp documents to sharp text on school and office printouts. Dear Customer, if you want predictable results without overpaying, this DrTusz compatible cartridge is designed to deliver the same quality as the original, with deep, clean black that makes every line look confident and professional.
With a capacity of 10 ml, this cartridge is made for efficient, hassle-free printing at home or in a small office. Its estimated yield is up to 240 pages (at 5% coverage), so you can plan your printing calmly—whether you print a few pages a day or prepare larger batches at once.

Under “Related products” you’ll also find matching cyan, magenta and yellow cartridges, higher-yield XL versions, convenient multipacks, as well as original OEM options and even a specialist head-cleaning fluid to help maintain smooth ink flow. And as always, we carefully protect every parcel before transport, so it arrives in perfect condition.
