This luxurious silver handkerchief is manufactured with a fabric called “Vega”. This is an elastic knitted product which composed polyamide yarns, that are metallized with pure silver. The high silver content of over 20% leads to the release of silver ions, which destroy microbials on contact. Studies have shown that Vega also has a high effectiveness against Coronaviruses, at very high speed. Coronaviruses are inactivated within 15 minutes after contact. The product is washable at 60°. Frequent washings and dry cleanings may gradually reduce the product effectivity and result in discoloration. Silver is a biocidal active ingredient according to §67 of the EU Biocide Regulation.
