This is a very intriguing cartridge filler  in brushed steel with the image of Mickey Mouse in relief both on the barrel and the cap. The same pen exists in silver as a limited edition of 2000 pieces with an identical image on cap and barrel but with a serial number and a gold nib. This pen has no serial and the nib is steel.

I have not been able to find so much information about it  apart from a few auction listings.  The pen does not say "Pilot" anywhere (nor does the limited edition) but the design of the nib clearly talks Pilot.

I suppose  this can be the standard edition corresponding to the limited edition which was manufactured as  a Walt Disney licensed product. 

The pen is is excellent condition.
