This is a Marukin mottled red hard rubber eyedropper pen c. 1930s. This Marukin red hard rubber swirl pattern eyedropper pen comes with a very unusual two piece cap. The top section of the cap, with the Warranted clip, can be removed so one can hold the pen using the black ebonite part of the cap as a wide grip. The two cap pieces can also be removed as one, as on a normal pen. In this case the two pieces are separated. The pen has a normal hard rubber section that matches the pen barrel. The Marukin nib is incredibly flexible. The nib was installed very deep in the section so only the long tines show when the pen is opened this way. It’s an eyedropper with a shut off valve. It operates as many other Japanese eyedropper pens by slightly opening the end cap to allow ink flow to the section. We have never seen another one like it! #pencollecting #fountainpen #marukin #redhardrubber #eyedropper #penhero https://www.instagram.com/p/B_K6cljjtGf/?igshid=1abjaeolmj80c
