Gel Knives - These are perfect for use with our line of Flocking Gels. The mini Gel Knife is great for bases smaller than 80mm x 80mm. The mini blade is straight and easy to manipulate. The #2 & #4 are best with larger bases or buildings. #2 & #4 are also angled to reach around larger pieces, *They are awesome for getting grass (medium gel) in the corners of a castle courtyard* See our page on Acrylic Gels for more details on our line of acrylic gels.
