Kendo Black Mouthguard for Adult 14-bar Men (for droplet infection prevention)

This is a mask guard for Kendo.
Protects against droplets and COVID-19.
For adult 14-line men'gan (face protector).
I bought a set of 2 and am selling one that I won't use.
While clear masks offer good visibility, the black type conceals the mouth area, making it stylish and cool.

Thank you for looking.

Please read the following carefully until the end. If you cannot understand, please do not purchase.
I will not conduct transactions with individuals who have a transaction rating of 2 or lower, or those who do not send a greeting after purchase. I will cancel your purchase if this is the case (to prevent recent Mercari issues such as item swapping).
I will lower the price at my own pace.
Negotiations for significant price reductions will be ignored and deleted.
Please check the condition in the photos. Only purchase if you understand that this is a used item, not a new one.
If you have any questions, please comment.
