I purchased these about 30 years ago for a parent-child performance, but they never got used and have been stored away. This is a set of three, in red, blue, and green. They are old, but still usable. All three are in the key of C. The entire set has been cleaned and disinfected with alcohol. They will be packaged in waterproof and bubble wrap and shipped via Yu-Packet Post. I am looking forward to purchases from those who understand that these are used items. (^^♪
