Cylo is a minimal Pen Spinning Toy. We love Pen Spinning but all the different parts and pens you have to acquire to make a mod can be a lot to deal with. Most pens have a lot of parts and pieces. We decided to create a minimal design for the people out there who want to keep their skilltoys simple. Cylo is made from a Delrin rod that is tapered in the center, and has three grooved lines on each end with Nitrile rings in them. You can remove the Nitrile rings to reduce weight, in which case the grooves function to provide grip or you can add other pen grips to your Cylo for your own custom feel.
