Dirty Fingerboards is based out of the Philippines and handcrafts illPills with incredible detail that you can see in their graphics. Their attention to detail is second to none and will leave you amazed at first sight. But not everybody needs all the bells and whistles! The Swirl color version of the illPills is for those who prefer a simple and clean look. This fingerboard wheel is made out of urethane, uses Dirty FB's Street Shape, and features a 70D durometer. This hardness will give you more grip than plastic wheels, but can still get loose and slippery when you powerslide. illPills also feature ABEC-9 bearings, which do have a locking system to prevent any wobble.
