12 Diving Mask Set - TUSA Brand - Used - Low Usage Frequency - No Damage

Purchased about 15 years ago at a specialty store as a set of three for around 20,000 yen.
It has been stored carefully, but the silicone rubber has changed from transparent to light brown. However, since the material is not rubber, it has not deteriorated.

It has been used in the sea about 15 times, so I believe it can still be used sufficiently.
As it is a used item, there are some minor scratches on the surface.
Please refrain from purchasing if you are sensitive or seeking perfection.
