Fisher Space Pen 50th Anniversary Apollo 11 Pen Pressurized/Sealed Ink = 3x Life For Sale

Pressurized thixotropic ink in a hermetically sealed, pressurized reservoir writes three times longer than an ordinary ballpoint pen. Stainless steel precision socket prevents leaking yet delivers uniform ink flow. Sealed with a gas plug. Write at any angle, under water and over grease. Too cool! Bought for my son’s HS graduation - selling ones I didn’t give to him (college is expensive!).
