Boobeen wooden nail brush is perfect for gardeners, mechanics, and other professionals whose hands are often exposed to dirt, grease, grime, paint, and other items that could get stuck under the nails. | While washing, massage the bristles around your nails for a few seconds. This will help soften the callus, giving it a gentle nudge, until it naturally falls off, leaving you with luxuriously soft hands and feet. | The gentle bristles are also effective in exfoliating those hardened skin around the nails. |
