This is a pair of Lyrisch ocarinas: a Primary AC pipe (beginner model) and a Harmonic SF pipe (one grade higher than the Primary). I have confirmed that both produce sound. There are scratches and stains due to aging. The AC pipe has cracks in the surface coating (not through to the inside), as well as small scratches and scuffs. It can be played with a light breath. The SF pipe is in better condition than the AC pipe. It requires a stronger breath. The high-pitched E and F require some technique, such as adjusting the angle and breath. The last image, 14, shows the original color of the clay at the mouthpiece. It is not nicotine stain. Please check the images for the condition of each pipe. I am a non-smoker and do not have any pets.
