More about our products and services: 

• Custom Sizes Up to 60 Inches (Length or Height) – We offer fully customizable, high-quality acrylic display cases crafted to your exact specifications. Whether you’re showcasing small, high-value collectibles or large-scale models, or require unique dimensions or support structures, we can create a display case that fits your collection perfectly. We recommend that you order a small display case to experience our craftmanship before ordering larger cases.
• Full Customer Support – This is a custom-made product, and we are committed to providing prompt, responsive support for all your needs. 
• Premium 4mm (1/6") or 6mm (1/4") Thick Acrylic – We use only 4mm (1/6") or 6mm (1/4") thick acrylic panels—never flimsy panels like typical display boxes that bend and feel cheap. Our boxes are two to three times thicker, noticeably more solid, and remain rigid even in large sizes. They not only protect your collectibles but also give them a high-end, premium appearance. Watch our video to see the difference in quality and feel.
• Steel Brackets & Screws for Maximum Stability – Typical display boxes rely on push-fit joints that easily misalign, loosen, and fall apart with minimal movement. Our boxes are secured with large stainless steel corner brackets and screws, providing unmatched structural rigidity. Nothing shifts—once fastened, the box stays perfectly aligned and sturdy.
• Sleek, Modern Aesthetic – Our stainless steel brackets and screws add both strength and style, giving each display a high-end, gallery-quality appearance. In contrast, typical boxes have visible slots and push-fit lines that break up the design. For a seamless, modern look with clean edges, watch our video comparison that shows the difference side by side.
• Securely Stackable With Brackets & Screws – Our display boxes can be safely stacked using brackets and screws, creating a solid, unified structure that won’t separate—even when pressed down. Typical display boxes simply sit on top of each other with no secure connection and can fall apart with slight movement. Each of our stacked units remains individually openable, allowing you to access your collectibles without rearranging the entire setup. Watch the videos in our listing to see how it works!
• Front Panel Opens Easily With Hand Screws – The front panel opens with hand screws, allowing you to place or remove large items effortlessly. It’s designed for maximum convenience without sacrificing beauty. 
• Openable Top or Raised Bottom Option – The top panel is also removable using hand screws, giving you the option to access your collectibles from above. You can even flip the box so the hand screws function as four feet, creating a raised-bottom presentation for an added touch of elegance.
• Please note: The Lego sets shown in the display boxes are not included
