Specializing in Brother products. I mainly sell multifunction printers, even among PC peripherals. I offer specialized maintenance that other sellers can't easily replicate, such as "replacement of the waste ink absorber pad" and "replacement of the print head," the core component. I also thoroughly clean (no ink stains) and disinfect with alcohol (for COVID-19 measures) to deliver a pristine machine. Please distinguish my products from "as-is" listings from others that are not maintained or cleaned. Therefore, please refrain from requesting price reductions. My listings are not suitable for those seeking only low prices. Also, if sold on other sites, I will end the listing here without notice. ※ Please also see my profile.
