Blackriver concrete obstacles are hand-crafted in Blackriver City and are the evolution of former "Bonsei" concrete. 

The parking block fits perfectly in your backpack and guarantees street credibility and the finest grind feeling!

Size: 19.5 x 2.5 x 2.0 cm

Attention: Fine hair cracks due to the slow drying process of concrete are normal and part of the realness factor of the material! The curb can be used as usual, it won´t break. Use wax to keep the surface of the concrete smooth, just like in skateboarding.
