This is a Kendo glasses [Tenbu]. The lens prescription is R-1.25 L-1.5. These are children's glasses. They have been used for about 1 year and a half. Since my child used them, the original case broke. I bought a replacement hard case, shown in the attached image. If the lenses don't fit, you can take them to an optician to have them replaced. Please only purchase if you understand that this is a used item.
