Each set of Ill Pills contains 5 (YES 5!) wheels. These wheels have hands-down the fastest and longest spinning bearings in any fingerboard wheel I have seen so far. The Ill Pills Street wheels have a diameter of 7.8mm which is about the size of Oak Wheels RV2 (7.9mm).
Material
Urethane
Ill Pills made from 70D premium urethane have more grip, however they are by far not as grippy as Oak Wheels. On a scale from 1 to 10 (no grip to super grippy) Ill Pills 70D are a 6/10 while Oak Wheels are a 9/10. If Oak Wheels are just too grippy for you and plastic wheels to slippery checkout the Ill Pills 70D. The white 70D material is slightly off-white which makes it look like a skateboard wheel straight away.
One set contains 5 Ill Pills wheels Street 70D White.
