To open up to contamination, even through a zip fastener. This is what Megazzini has done through an alliance with YKK, the world leading company of zip fasteners and small metallic accessories, for the creation of ‘Ykey’. This precious key-ring with pop flourishes (it may also become a pendant for bags, necklaces, and mobile phones) combines the design quality of both companies sharing the same production philosophy, based on the highest quality and a sense of helpfulness to the clientele. Megazzini, a company from Valenza, is not new to brilliant small/great ideas of the kind. Suffice it to think of Jokinoro, a very original line of charms in gold and enamels. Founded in 1947, the company is known and appreciated for its specialization in the production of claps for pearl strings (there are over 5,000 references in its sample book). The company has had the ISO 9001/2000 certification since 2000.
