bRRRush, aluminum handle

While bRRRush is using the revolutionary N.era tips, a unique
”vibe zone” has been machined on its handle.
When letting the nail of your forefinger stroke back and forth
on the surface, you create a micro-vibration which
propagates up to the very end of your brush tip. The
small portion of porcelain on your brush will almost
“detach” while transforming itself into a small drop very
easy to apply to your build-up.
The advantage of this technique lies in the fact that much
less air is integrated in the porcelain during build-up,
synonymous with less porosities in the porcelain
after firing – spectacular especially in the incisal area.
