Each non medical grade mask is made with 4 layers
* 2x 100% cotton layers
* 2x non woven interfacing (polyester)
* Tabs are cotton
* Elastic is polyester (not latex free)
* Wire is encased in plastic
These (non medical grade) masks have darts at the sides for a snug fit, they also have wire that sits across the bridge of your nose for improved fit. Elastic is not sewn into masks, instead it is threaded through 4 loops. You can use the loops to either thread through elastic or ties.
I do not supply material for ties, but shoelaces work really well if you prefer to use ties. Otherwise, I supply enough elastic to go over the ears, if you need longer lengths (for around your head), please let me know. I have found that allowing people the freedom to determine length, often results in a better fit, please be sure to adjust the length to best suit yourself though.
I recommend washing in cold to warm water to improve the lifespan of your (non medical grade) mask & air drying. When the elastic wears out, simply cut & restring.
Please remember these non medical grade masks are not a failsafe, you still need to exercise caution when in close proximity to others.
