All shuttles are AEROSENSA700. Regarding the shuttles I am using, I believe they are in good enough condition for use as practice balls, etc. They also come with various speed numbers mixed in. Please refer to the photos to judge the condition of the shuttles. If you would like to know more details about their condition, please leave a comment and I will add more photos. While some shuttles are in good condition, please understand that some have chipped feathers. Also, returns are not accepted. I want to sell them quickly, so I am open to price negotiations!
