yuwellAdult Oxygen Mask with 6.6' Tubing and Adjustable Elastic Strap - 4 Packs

It comes with 2 masks. One was a little sharp where the plastic was cut and was irritating so I returned it but I don't think I would had wore it much otherwise. Found out I'm not a mask person

The Yuwell adult oxygen mask came with four masks and tubing. The mask fit securely and comfortably over the face. The attached strap also kept the mask firmly over the head.The tubing fastened adequately in both the mask's end and a standard oxygen tank. The air flowed effortlessly.I would rate this product as a good option for anyone with a supplemental oxygen need.

Well, I thought this set was for nebulizing, but it isn't and the tubing doesn't fit a nebulizer. However, you get four masks and four tubes, so it is a good deal. Also, the masks fit nice and snug, and the tubes are quite long
