123 cartridge (mustache)
tried this company for toner. had a bad cartridge. drum was defective. no service to replace the defective part. not a recommended company. try others. hope this helps others that are looking for compatible toner or ink. Started to get bad after i installed 6 months after i received the cartridge. warranty is for one year. well the the drum went bad after 1 yr of receiving the cartridge. conversation with them by email pretty useless. hope this review helps others thinking of buying from 123 cartridge or "mustache"
