We are not responsible for the foil once you start handling it. The smallest burst of air can flip the foil over, bend it, or tear it. If you fold the material on accident you can smooth it out easily by putting it back in the tracing paper and running your fingers over the tracing paper until it is flat again TipsUse a cutting mat not a cutting board. You can find on amazon or a local hobby store.Make sure to clean the mat of debris to keep your cut nice and straight.Use a very sharp cutting tool (exacto).Cut slow and steady. Avoid starting and stopping.We like to keep the foil between the two sheets of tracing paper when cutting it to the desired width. This will help to avoid tear out on the edges. Buy some extra tracing paper to store the foil because every time you make a cut you will also cut the tracing paper and eventually run out of the supplied tracing paper.Use a flat ruler as a guide and apply enough pressure so the material doesn't move on you. Cut the ribbon to an over sized length. We like to cut a piece the entire length (longest dimension) of the raw material to make sure we can handle and install the ribbon properly.Have patience. It takes some practice. Try practicing on regular foil first to see how the material responds to cutting. You can also buy some 0.3µ-0.6µ imitation silver leaf to practice on. If you can cut this you will have NO PROBLEM cutting a thicker foil.CM-9888 Specifications Impedance Ratio ~ 0.19 : 150 (1 : 28)Twin BobbinOperating SpecsMechanical Specs Domestic Shipping Shipping is free for any number of transformersInternational Shipping The will ship priority international mail Returns Returns are accepted within 14 days after you receive the kit.International Buyers – Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost.
