I purchased these new, but they didn't fit, so I've only tried them on. The size is 27.5cm, and the color is black. The original box was damaged, so I will ship them in a new box for a 26.5cm pair that I repurchased. Please only purchase if you agree to the following: ① Please refrain from unreasonable price negotiations that are far from the listed price. Also, please be sure to state your desired price. I will not respond to generic comments like, "Excuse me, I'm considering buying this. If you're willing to lower the price, how much would be possible?" as these often result in no response. I may block you immediately. ② Please do not purchase if you are prone to giving negative feedback for selfish reasons or on a whim. ③ Please ensure that you conclude any questions you ask. I am very inconvenienced by people who ask questions about price negotiations or size and then leave without responding, so I will block them immediately. ④ The perception of condition varies from person to person, so please judge based on the photos. If you would like additional photos, please do not hesitate to ask. ⑤ I try to be as courteous as possible, but this is a product inspected and listed by an amateur, so please refrain from purchasing if you are looking for a perfect product or service. I carefully check for noticeable stains and scratches, but I cannot accept returns even if there are any. ⑥ To reduce shipping costs, all foldable items will be folded for shipping. Please let me know before purchasing if you have any requests. I apologize for writing so many strict conditions. Most people are reasonable, but I have had unpleasant experiences repeatedly due to a few unreasonable individuals, so I appreciate your understanding.
