Stealth Line Arrows

We are occasionally asked, "WTF black line arrows, are those real or an April fools joke?" Once-upon-a-time (so we were told) when the injection mold was built for the line arrow shape, the initial manufacturing test run was made using stock polystyrene that was black color... so yeah, sadly they are real. Eventually, we were talked in to taking some with our logo silkscreened to serve as sort of business card promotional handouts at dive shows. Apparently, the supplier gleefully shipped us everything they had. Stealth line arrows are a physical oxymoron - serving no useful purpose in diving that we can see (get it?), but we still have some Black color blank versions taking up space in the warehouse.

The stealth line arrow is a limited edition collectors item... some day they could be very rare and valuable... or not.
