Brass
OBJJP's brass products are not painted. This is part of the design and facilitates the ageing of the metal surface. They create character as they are used by the user. If you want to maintain the shine of the surface, you can polish it with a soft cloth using a metal polish.
Leather
As a natural material, leather tends to blend in and become better as it is used. Leather is highly moisture-absorbent and breathable, and is often finished with a dyeing method that allows it to take advantage of its characteristics and surface texture, making it difficult to completely stop the color from occurring.
Lighting
OBJJP's lighting products are rated at 3A 300V 50/60hz. The plugs are also designed to Japanese specifications, please use your country's converter. The set screws on the bulb socket are coated with Loctite. Please do not disassemble it.
Oil Burner
Once the oil burner has cooled sufficiently, wipe the oil well with a clean, damp cloth or mild detergent. Then let it dry thoroughly.
