Founded in 19th century by our great-grandfather Hacı Tahir Efendi in Kastamonu and worked on importing & exporting from Inebolu Port during those dates, our family company continued its commercial life thanks to our grandfather Hafız Ahmet Bey. After him, our father Abdullah İşeri took the business over and provided service in hardware and spice sectors. Today, our family company still continues its existence. In 1970, with the opening of Kastomonu Industry Market, Selahattin İşeri and Sedat İşeri (sons of Abdullah İşeri) founded İşeri Biraderler Tic. ve San. Koll. Şti; started to provide service in hardware and car material sectors and enlarged the scope of our family company. In 1984, a respected firm called OTOLUX located in Karaköy, Istanbul was taken over and our Istanbul based company was founded under the name of İşeri Biraderler.
