This is my concept for the knuckle roller: the Zen Roller. The Zen Roller's (ZR) uniqueness lies in its magical sound. Similiarly to the baoding (Chi Kung) balls - when you move the roller between your fingers, you can hear a nice soothing, jingling sound. The slower your moves are, the more gentle the chimes in the balls become. You can think of it as a 'mindfulness roller'. (Of course, you might as well roll it like there is no tomorrow, if you like. :))
Now, all my rollers are made with a special silicone rubber, so they're kinda grippy. Therefore, to do stunts with it, you need to keep your finger muscles more relaxed - compared to a heavy, polished metal roller, for example. The more relaxed grip you are able to maintain during your moves, the faster you can roll it. Just play with it, explore it, and you'll get the flow soon. Move slow to learn fast!
You can find a short video showing their sound on the shop's Instagram feed:

****** What is a knuckle roller? *******

It's a skill toy. A fidget device. A mindfulness gadget. Something you can play with when you're bored, waiting for something, when you are stressed or basically whenever you like. You can learn spectacular stunt moves with it, or just roll it up and down between your fingers. You can even improve your fine motor skills.

************ ZR parameters ************

The ZRs are handmade by me (except for the balls). They are all unique products, you will not find two identical. They can differ in neck thickness, length, weight or even sound pitch and volume. If you order, you will get a datasheet (some guys call this COA, but I come from the engineer world :)), so you will know the exact parameters of your particular one.
You can see the actual datasheets on photos of the listings. Explanation of the values on the "Size" field (just an example):

| | |
| | --> Neck diameter at it's thinnest part
| -------> Ball diameter at the ends
-------------> Total length of the roller

Oh, speaking of engineering terms: if you buy this ZR, then WYSIWYG, which means: What You See Is What You Get - the photos are not sample photos (except for the pouch).

************** Zen Pouch **************

You can choose to get a minimal design black leather pouch with the ZR. The pouch will protect it from your keys and/or the scratches of any other metal EDCs in your pocket. (On the sample photo of the pouch you can see it in action with my prototype roller.) For now, the Zen Pouch cannot be purchased separately, only as an add-on to your Zen Roller. I usually have other, one of a kind leather pouches as well, but those are usually a bit more expensive as they are designs with hand stitchings.

************** Custom ZR **************

If you would like to order a ZR with special color for yourself, please contact me, and we'll see if I can make it for you. Shipping of custom orders with colors I do not have in stock could take up to 4-5 weeks from date of order.
