WATERPROOF BRUSH TECHNOLOGY
The newest generation of Sigma Beauty brushes feature patented interlocking ferrules with double-threaded engineering. This exclusive technology, invented by Sigma Beauty, is an innovative screwing system that tightly attaches the brush handles and ferrules, unlike conventional brushes which are typically glued and pinched.
Made with solid, polymer-based handles, these brushes outperform brushes with wood handles. Wood handles expand and contract when in contact with water which causes the ferrule to separate from the handle after multiple washes.
The tight seal created by the interlocking technology, combined with the solid, polymer-based handles make our brushes waterproof. This means wetting the handles and ferrules during brush cleaning is no longer an issue because moisture won’t seep in.
