We use a high-quality acrylic glaze that has 3 grades. For more valuable pieces, we use the highest grade – Tru Vue Optium Museum Acrylic. It offers 99% UV protection, anti-reflective, anti-static and shatter-resistant. For a lower price, we have the second grade that offers similar protection; it is also 99% UV protective and anti-reflective. The next grade is the cheapest and used for less valuable artworks such as posters and souvenirs.
