Produced from 1981-1989, the matte finish Slimline was created as a slender model to compete in the market with the Aurora Hastil. The fully brass body allowed it to operate with less susceptibility to cracks. This body was then coated with the gorgeous matte finish seen here. It was fitted with a stainless steel, gold plated nib that simply stated "MB" - an appropriate indication to the simplicity of this pen.
This particular pen is in very good used condition. It comes without the original boxes and papers.
