Particularly worth collecting are older ink bottles from Montblanc or Parker from the 1930s. In the current market offer, especially Montblanc bottles including the Season's Greetings and the rose-ink editions, Diamine (classic, e.g. available via missing-pens.de from Rolf Thiel) as well as Caran d'Ache (very beautiful, although with little ink content) are mentioned. Complementarily, Caran d'Ache, OMAS, de Atramentis (with scents) and Visconti are positively highlighted. Differences in taste are pronounced here; one's own selection by visual preferences is usual.
