I purchased these on January 10th and tried them out, but they didn't suit me, so I'm putting them up for sale. I realized they weren't a good fit after using them a few times, so they're practically unused. Part of the box was torn when I opened it. The ear tips themselves are fine. They have been wiped with a disinfectant wipe. Please understand that these are used items. Ear tips for high-end wired earphones, made of medical-grade silicone (1 pair, size S)
