This solid Titanium Piston Ring is the perfect Valentine’s day gift for an engine-loving partner. The ring looks extremely sharp and includes a piston that actually works, which is quite gnarly. As the thumb wheel rotates around, the piston on the ring goes in and out in perfect harmonic motion.
Not only is the Titanium Piston Ring swell due to its technically accurate design but it is also extremely durable due to the actual titanium used as its material. The ring does not deteriorate by water or chemicals and will be a lasting memory item for your beloved one. It may be the smallest working pistol on the market currently and the fact that it is in a jewelry form makes it all that much grander.
