Weight for underwater camera housing

Thank you for looking.

This is an Olympus Balance Weight PWT-037.
It weighs 385g and attaches to the bottom of TG and PEN housings to adjust neutral buoyancy underwater.
As you can see in the photos, it is covered in plastic overall, but there are some scratches (photo 4) and transfer of print (photo 5) in some areas. However, this does not affect its use.
It was only used in the early days, and later became unnecessary as I started using strobes, arms, lights, and other equipment, so I am now selling it.

Manufacturer's price: ¥4,180 (excluding tax)
