Four search-result fragments constitute the entire known record. A '6x6 cube unboxing' video description names www.mertsagdinc.com as a website and links a page for private lessons. An 'ANKARA COMPETITION' post cites mertsagdinc.com/ana-sayfa and a Rubik's Cube learning PDF. Two Instagram posts — 'Aysıtı-3 Kıraks-1' (July 2023) and 'Renkli küpler, daha renkli insanlar' — show the same handle discussing competitions, the latter referencing an Istanbul venue.
What cannot be established is equally important: the site's full page structure, the terms or pricing of the lessons it mentioned, and the date it went offline. No snapshot exists in the web archive and no company card is attached to the name. Any claims about the domain beyond the fragments above should be treated as unverified.
