The Martelli Machine Cleaning Brushes are verstatile and can be used in numerous ways. They are perfect for cleaning those tight spaces in sewing machines. They attract lent and debris like a magnet and can actually be magnetized by rubbing them against a magnetic surface then held over dust and debris that will rise to stick to the bristles of the brush. Additionally, they are great for makeup application and work in a similar way as they pick up eyeshadow and other powder foundations easily and the bristles are super soft, so they are safe and comfortable for makeup application. They've also been used at office desks and workstations to clean lent and debris from computer keyboards, telephones, and other items. They're stylish and the handle has an ergonomic design made to fit perfectly in your hand for comfortable use. The multi colored bristles and metallic handle look great for make up artist, quilters, or seamstresses that want a tool that looks as beautiful as their creations. They also make great gifts!
