(World Coral-Reef Conservation Society). Coral reefs are called the "forests of the sea" and are habitats for various marine life, as well as a source of oxygen through photosynthesis. When the EL backlight is activated, a manta ray, which is admired by those who love the sea, appears, and the W.C.C.S. logo mark is engraved on the back. The battery is dead, so the operation has not been confirmed. This is a product from over 20 years ago. There is a feeling of use and damage. There are scratches, stains, and damage. Since this is a layman's inspection, there may be scratches that were overlooked in addition to those shown in the photos and descriptions. Please understand that this is a layman's storage and a layman's eye. It will be packed with cushioning materials and shipped to prevent water damage. Instant purchase is possible. Thank you.
