Vaessen Creative Embossing Tool Set Creasing Pens. This embossing tool set from Vaessen Creative consists of three creasing pens of different sizes. Creasing pens are ideal for creating crisp scoring lines in paper and cardboard. Move the creasing pen along a ruler on the line where you want to make the fold and press lightly to make a crease. Then fold the paper along the crease to fold a crisp line. Scoring the paper first helps to prevent the paper from breaking or tearing. The embossing tool comes in handy for card making. This embossing tool set contains creasing pens in the following sizes: 2-6 mm, 3-8 mm and 8-12 mm. The tool set is also perfect for shaping circles cut with the Bubble Craft die to use with Bubble Craft clear stamps to add a 3D effect.
