Printing since September 2025. My first printer was the A1 mini. I had an idea for protecting cards in top loaders. I never liked that dust seemed to alwats find a way into them. My first design was the Top Loader DUO - Originally named because it uniquely displayed both sides of the card and my first deaigne held two cards at a time. I wanted to also give a graded feel to my cards so thats why there is a clear space around the displayed card. My design is patent pending and I have since created the DUO bumper guards and the Slab DUO. The DUO represents guard and display.
