Product Description
Type Multipen
Product Name Double Action 3, it seems similar to the MWB-5000 line and could be a earlier model.
Manufacturer and Year Platinum, Japan -- probably the 1990s. (A bit different from the current style Double Action pens)
Length 5-9/16"
Filling System The ballpoint portions take D1 refills. D1 refills are the slim multipen refill. The pencil takes 0.5mm refills. The mechanism works by choosing which writing instrument you want, rotating the pen so that its label is facing up and then pushing down on the cap. Twisting the cap releases the mechanism. Working red and black refills are installed.
Color Marbled green body with gold plated trim.
Condition Excellent condition. The pen has handwear but perfect trim and imprints. The mechanism works well and the eraser looks perfect.
