Fisher Space Pen SU4F Adapter for Olight O-Pen2 by lightmaster8243

Last crawled date: 4 years, 9 months ago

This is an adapter that allows you to use a Fisher Space Pen SU4F with an Olight O-Pen 2. The refills can be readily purchased from eBay and Amazon from a variety of sellers. You MUST use the Fisher Space Pen SU4F refill as it is the only one that is short enough to fit within the O-Pen 2. Furthermore, prior to inserting the refill into the adapter, make sure you snap off both of the 2 extenders attached to the Space Pen refill. They do not contain any ink and are only there to make them long enough for some other pen bodies.
