TIRTIR Mask Fit AI Filter Cushion 21C & 17N This is a sample set with two colors, 21C and 17N, and a puff. I had intended to use it, so I've taken it apart. The puffs have been removed from their packaging, but I haven't opened the lids of the two cushions, so they haven't dried out. The puffs will be sent in a plastic bag, etc.
