YAMAMOTO 7500 N95 Mask (19 masks) I purchased these new and used only one. The other 19 masks are unused (individually wrapped). * No comments needed, immediate purchase is welcome. ● Other Notes: * When packaging, I will cut out the instructions, how-to-wear guide, and precautions section from the box and include them in the bag with the masks for shipping. The actual product may differ slightly from the photos due to shooting conditions and the environment. Please understand this before making a purchase.
