This is a product from Shimizu-zaka Glass Kan. These are "Piari" earrings that are comfortable and won't hurt your ears. The size is L for both ears. As the urethane pads have just been replaced, they will be considered new and unused. (They were only tried on before replacement.) Although unused, they have been stored by an amateur, so we await purchases from those who understand this. As urethane pads have been replaced, the main body will be placed in a zip-lock bag and shipped wrapped in bubble wrap.
