Electromagnetic wave shielding apron with buttons

This is an electromagnetic wave-shielding apron that I received.
There is a mark like ink leakage on the pocket area.
There are no tags or labels.
It is made of the same fabric throughout, not just in parts.

Recommended for pregnant women, those working in the kitchen, or those doing PC work, and anyone concerned about electromagnetic waves.

Not in pristine condition, so please take it at a low price.
- Color: Navy
- Design: With buttons, with pockets
- Material: Unknown, but smooth texture
- Shape: Sleeveless
- Button color: Light blue

Thank you for looking.
