With the non-flexing Artist Bridge you will never smear or smudge your artwork again because you are always resting an 1/8�۝ above your work. The clear acrylic allows you to keep an eye on your work at all times. You can control all soft and wet mediums with confidence, whether rendering details or cutting in accurate line work. Use paintbrush, pastels, charcoal, markers or airbrush with professional results every time!
