These were acquired from an old magician’s estate and were found in various locations. We made them up into a lot of twenty miscellaneous mouth coils. Some appear to be Londono Coils, and the rest we are not 100% sure of the maker. All are new and have never be used. On some the holding tape has yellowed from age. There appear to be four coils that are at least 25 feet in length and the largest is 46 feet. On all the others, can’t be sure of length, but would say they are at least seventeen feet for sure.
