The Quick Trimmer is a versatile trimmer. It is perfect for trimming thin paper strips as in sentiment strips, and it easily cuts foil to size for the Hot Foil Machines. It helps to reduce waste and doesn’t scratch the medium surface. The set includes one self-healing mat, one trimmer guide, two cutting blades + two cutting blade sleeves. The mat and guide are in both metric and imperial measurements (inches and centimeters). Replacement blades are available as T-018 Quick Trimmer Replacement Blades. To cut, sandwich the foil or paper between the self-healing mat and trimmer guide, determine where to cut, place the blade down into the channel, and glide your blade to cut the material.
