Then look at thickness. This matters more than most people think. Thin cases, like 2mm or 3mm, bend easily under weight. A good protector should feel solid. In our design, we use 8mm acrylic for the four side walls. The top lid and bottom are 5mm. Why the difference? The thick sides handle stacking pressure well. The slightly thinner top and bottom keep the case from being too heavy. You get strength without bulk.
Another thing we learned: do not make the case too tight. Some brands make the fit perfect on paper. But in real life, a super tight fit scratches the ETB artwork when you slide it in. We always leave a small gap. It is safer and keeps your box looking new.
What should you skip? Stay away from cases with visible glue lines on the corners. That is a sign of poor construction.
At the end of the day, an acrylic case is more than plastic. It protects your ETB from dust, bumps, and stacking damage. It also makes your collection look cleaner and more serious on the shelf. We make our cases with that in mind – simple, strong, and built to last. Take your time choosing. Your cards and your ETB boxes are worth it.
