50 shades of blue #37 Lamy (Royal) Blue

Lamy (Royal) Blue is one of the many (generic) royal or washable blues that are the standard in European schools for writing.

Many children use a Tintenkiller (ink eraser/eradicator) to erase mistakes and write over the now invisible line with a felt tip that is attached to the second end of the Tintenkiller pens.

The WingSung 3008 pen you see belongs to my 12-year old daughter and is used in school.
