USA-made, NIOSH-approved Jackson Safety N95 Respirator Masks, Pack of 50, Large

64245, R10 Brand new, unused N95 respirator masks. "Duck-bill" pouch style. (The loose one photographed is from a previous order.) Made in the USA. 1 pack of 50. The size is called Large, but it's the same as the Kimberly-Clark standard size for an adult. (SureWerx is affiliated with Kimberly Clark, and as far as I can tell, these are identical to Kimberly Clark ones--just more affordable.) NIOSH approved.
