A leaf was taken from a moss (from the gametophyte stage) and viewed by brightfield microscopy. Moss leaves are only one cell thick and consist of an array of regularly shaped cells. The lighter area in the centre of the cells is the vacuole, which is an aqueous storage compartment, and the darker green organelles around the edges of the cells are the chloroplasts which capture light energy in order to photosynthesise.
These facemasks measuring 13 x 17.5cm have a full coverage print on their polyester front with a soft white cotton reverse. They come complete with 2 replaceable PM2.5 filters (8.5 x 12cm) that fit in a pouch between the outer and inner and soft elasticated ear loops (which come with rubber gromets to adjust for size but I normally just tie a loose knot in the elastic).
Please note that these are not medical grade masks but they are perfect for general use.
(Washing instructions - facemask machine wash at 40C, PM2.5 filter handwash. PM2.5 filter can be replaced with folded up kitchen roll.)
