For beginners with small budgets eBay is basically usable, provided the pictures are clear and nibs do not appear bent; prices in very good condition lie mostly in the low three-digit euro range. At specialised dealers prices are higher, in return with checked condition and partly warranty. Nib designations like 'OM' or 'OB' mean oblique (slanted) and enable calligraphic effects, although these arise more from nib-slit work than from pure slanting. The hyphen '-' in model designations indicates older pieces, partly made of celluloid; in everyday life these are easy to care for but should not be subjected to strong pressure or falls.
