The new QuadRoller fidget incorporates a series of repurposed roller chain links that are strung onto two rings. Each section has two sets of 2 free rolling stainless steel and 2 latex free rubber rings that are wrapped around each roller. Roller chain links are larger than regular bike chain links giving it a very solid feel.You can walk it over your knuckles or maneuver the links through the rings. As an added bonus, the quadruple free rolling center rings also allow you to roll those individual sections with your fingers. This has become one of my all time favorite fidgets. It's small enough to lay flat in a pocket, or you can arrange it into mini industrial style art sculptures to sit on your desk. Best of all, it's quiet so it satisfies the need to fidget without disturbing people around you. The new QuadRoller is a great fidget and stress toy for both adults and children to help relieve stress and anxiety, assist with focus, and build finger dexterity and fine motor skills. Size: 2.0" x 1.0" x .5" Weight: 1.2 ounces. Available colors include Black, Red, Blue, Light Blue, Green, Yellow, Purple, Pink, White, and Orange. Each fidget is handmade with great attention to detail. Due to the use of repurposed materials, color and overall link size will vary depending on available repurposed chain links. Each fidget is unique with its own individual characteristics.
