This is an unopened, unused earphone jack. This is a protective cover for a smartphone's earphone jack, and the back of the black cat embroidery appears to be a smartphone cleaner. The size of the main body with the cat embroidery is approximately 6.5cm x 3.3cm x 0.5cm. For those who love cats, why not carry this adorable black cat with you on your everyday items? I will sell this to someone who understands that it has been stored at home.
