Every product that passes through our hands bears the signature of Ladislav Ševčík and also may be marked with a serial number or as a limited series. Each product is accompanied by a certificate that guarantees its authenticity. Every such certificate is signed by the company owner and all those who took part in its creation and production – the artist, glass cutter, engraver. The certificate also includes the name of the product, its serial number, date of creation, and a description of the item. All this confirms the originality of the product. A certificate necessarily must accompany each of our products. If there is no certificate, it's not a genuine product from the Ladislav Ševčík company.
Since our glass has started to be copied – and not just the designs, but also the protected registered trademark – proof of the product's origin is important to us.
