When we only have medium size of pens for Maki-e works, we felt we need bigger pens for better Maki-e works, and we therefore, made Mikado for that purpose in several years ago. This pen uses Eye Dropper system. It is 6 3/8” long when the cap closed and diameter of the barrel is 13/16” heavy. The Maki-e on this pen has been very good because of its big space. The nib is size #8 in 18k gold available with F, M, B and Stub.
