A set of 12 high-quality YONEX AEROSENSA 400 feather shuttlecocks. - Brand: YONEX - Model: AEROSENSA 400 - Quantity: 12 pieces - Type: Feather shuttlecock These are used shuttlecocks that were used for matches and basic practice by an adult team. I believe they are still usable!! A mix of AEROSENSA 400, 500, and 600. There are more 400s. All 10 shuttlecocks in the box were inspected and distributed evenly. Grade A: No broken feathers - 4 pieces (front of the first photo) Grade B: 1 broken feather - 5 pieces (middle of the first photo) Grade C: 2 or more broken feathers - 3 pieces (back of the first photo) This batch has more 400s, but I am selling them because I still have some stock left from previous use! The price is set at this level due to the overall good condition. I plan to list similar items every 2-3 months. The price will vary depending on the condition. They will be shipped via standard mail, so delivery will take several days. ○ We also sell them in sets of 3 for 7050 yen!! Thank you for your consideration. ⭐︎
