Traditional BI wheels have bidirectional spines, so BI wheels provide 2D effect based on linear concept.
The 3D Cog is 120º barbed and provides strong lift.
The 6D gear guarantees the strongest lifting effect with an optimized 60º protrusion.
> 6D technology is one of the most advanced technologies for the production of gear teeth.
With 360º Hexa-spikes of our 6D technology, it guarantees a stronger and more stable result compared to conventional types.
> 6D smoothes and supports skin tissues in various aspects for a long lasting effect.
Strengthens Skin Lifting Effect
> Full Bearing Capacity, Traction and Pulling Force
> The April Bride 6D's Hexa barbs are made in 6 Dimensions to optimize and maximize the lifting effect.
