Kaiko Mega Cog Fidget

This the same size as a 50c coin. At 40 grams it makes it beautifully weighted as well and a great size for adult or big hands! 

Please note each OIL SLICK varies in colour as they are all unique. Each side of the cog is even different!  

This has a super fast spin, soft vibration & slight hum which is amazing. Rolling the cog over hands and fingers gives great sensory input.   Some like the way it "tickles" when spinning. The bearings that drive this are the smoothest I've ever used. It's incredible...

It is easily operated one handed. Please note that you need to tighten the two flat metal parts up from time to time. They just screw together holding the cog in the centre.
