'Sellotape' is one of (if not
The, for a while at least) leading brand names for 'sticky' tape products etc in the UK & Aust.... And over time the brand name has become universally (in those countries anyway) used to refer to any 'sticky' tape products.
Just like here in Aus we use 'Texta' to refer to ANY marking pen altho it's been a few decades since Texta pens were the leading brand sold here; or how we use 'Biro' for any ballpoint pen, even if it's a Bic or Parker or anything else.... :sour:
This'll all probably change in a generation or two.....[/QUOTE
Similarly in the US, duct tape has become "duck" tape.
