This supplier could be my first bad experience on this platform. They sent the mask in a very poor package box , which was compress in shipping. This deformed the soft rubber and frame in which prevent sealing to face from and chemical fumes. Supplier refused to refund or send me a new mask. In the end was told to return for a refund . Upon going to return item found out return shipping was 100.00 and there address does not come up in the data base. So buy with caution ⚠️.
