Schwan-STABILO also manufacture the Schwan line – “Schwan” being a swan, derived from the name of company founder Gustav Adam Schwanhäusser.
The Schwan pencils I have are curious – a yellow version, the Schwan 305, marked HB=2, and a wine coloured version, the Schwan 306, marked HB=21/2. The 306 is also labelled with a barcode.
The 305 is a decidedly darker lead than the 306.
The pencils have unfinished caps, and appear to be in more of a discount line than the Othello.
The 305 lead broke both while writing and during sharpening. No problems were encountered with the 306.
While the simple styling is a plus, I don’t expect pencil leads to repeatedly fracture in anything but the cheapest of pencils, so these are a disappointment.
