Dear Suppliers, I would like to request for no-logo 3ply washable mask with built-in filtration sheet. I do not need any replaceable virus filtration sheet. Please propose to me your specification and the certification to prove your specification. You can propose to me with your mask but preferable with the specification that comes with: 1st layer waterproof 2nd layer antibacterial knitted fabric 3rd layer microfiber interlock. Please send in your quotation to my email ivythenaces@gmail.com as soon as possible. Thank you. Show More
