Very interesting this, without knowing all the in depth production of the various kits, I can only ASS u Me that the price causes a pen to be high end. ...
BUT
My other main interest is fishing, which I probably know more about that Pen Kits.
A product, say a rig wallet is made in a factory in the east somewhere, then a label is applied ......
Low end company now sell them for £5.00
A well known company will sell the same rig wallet for £15.99 because it's name is on it
Same Quality, Same Product but is the dearer one considered High End ??
