A thin section was cut by hand through a rose stem and stained with Toluidine Blue. Viewed by brightfield microscopy, the cells at the centre of the stem can be seen, with the cell walls stained slightly differently depending on their chemical composition. An unusual and interesting view of a rose!
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.)
