BioBleach hard is DREVE’s blank made of Polyethylene (PE) — firm, developed specifically for tooth-whitening trays. Firm PE holds shape for durable, well-defined trays. Pair with Drufolen W for precise gel spacing. Ø120 mm.
A tray purpose-built for whitening means a better seal, less gel waste, a happier patient — not a repurposed splint foil.
