From many years of experience, we've been able to perfect the quality of our products. We've put the icing on the cake by fully hand polishing the entire exterior of the tank, providing a museum quality appearance. But we didn't stop there. We also hand polish the inner bracing of the 2 openings as well as the opening above the overflow box. We go above and beyond to provide our customers with a "show" tank that they can "show off". If the sizes listed is not what you're looking for, contact us as we specialize in customization from size, color of the background and base as well as the placement of the overflow box.
