I received this as a hand-me-down several years ago, but I've never used it (I didn't even know how to use it) and it's been sitting in a drawer. All accessories are included. The mask has some slight signs of use as shown in the photos (photo 3), but I have not used it. For those who need it, and those who understand that it is a used item. The OMRON NE-C802 is a nebulizer perfect for respiratory health management. - Model: NE-C802 - Brand: OMRON - Accessories: Mask, tube, storage bag, character figure - Colors: White, Green, Blue, Pink Thank you for looking.
