I purchased these from the official online store of La Villa de Pickles (ラ ヴィラ ド ピクルス). I intended to add prescription lenses, but was told that while the lenses can be replaced, prescription lenses cannot be added, so I am putting them up for sale. The following is an excerpt from the official description: These are eye-friendly glasses with a lightweight and durable resin frame. They offer high performance, cutting UV rays, blue light, and near-infrared light ◎ They have non-prescription lenses and are perfect for everyday use. [Material] Resin [Size] Approximately 13.3 x 3.3 cm Temple length: Approximately 14.5 cm [Country of Origin] Japan [Seller] OS Planning Co., Ltd.
