I designed the original "Pen Leash" for customer check out areas in stores and restaurants.They have proven to be more effective and cost saving than the chain pens. My design uses a 550 lb cord with a receiver that accepts stick pens. The BIC stick pen is the pen of choice. When at pen runs out of ink or is lost, simply insert a replacement stick pen.The cord will not break and will last for years. Since the Customer Service Pen Leash, I have designed a pen leash for a clipboard. This is a very popular item. Fisher Space Age Pens asked me to design a lanyard for their pens several years ago.
