I bought the 20mm tape thinking it would fit my paddle (Selkirk Invicta Power Air). Turns out the length of each strip is so short it would take three of the strips end to end to cover the entire paddle edge. If you are just going to put it on the end of the paddle for edge protection the length would be fine. If you want a continuous strip that protects all edges and covers lead or tungsten strips for additional weight it will take all three. With the edge guard tape I have been using (trimmed to fit the paddle width) I can get three strips for around the same price, but I does not have the pretty Selkirk name on it.
