Pellianni's masks are made of sustainable materials and the base of the mask is made of 100% Australian merino wool. Merino wool felt is non-toxic and environmentally friendly, as well as completely biodegradable, non-flammable and safe. The glitter fabric has been tested by CPSIA to ensure it is not harmful to children or the environment in any way, as are the PU materials. We offset the CO2 emissions that our masks create during production and the journey to us. Our goal is to leave as little negative impact on the environment as possible, complies with European standard EN71 1-3, ASTM and CPSIA.
