These give similar sensory input to our infinity cubes. Made from metal, both colours infinitely flip over and over in the hands as you manipulate the fidget. More of a two-handed fidget, the flip action provides some resistance also. 

The Gunmetal Infinity Triangle is the lighter of the two weighing approx. 80 grams (Aluminium) & the Oli Slick Infinity Triangle the heavier (Zinc Alloy) - weighing approx. 170 grams
