RONA is the world’s first company to introduce the "pulled stem" technology in the glassblowing process. This technology significantly enhances the mechanical strength of the product, thus extending its longevity. RONA uses lead-free crystal, providing its products with exceptional brilliance. The "clarity" of the glass remains intact after 1500 dishwasher cycles, ensuring a level of durability and resistance that will be appreciated for many years. The products combine elegance and technology with creative design.
