Transformers Optimus Prime Acrylic Display Case Our special hand-crafted cases were designed to offer added protection and enhanced display options for your collectible toy. Cases are available in two material options, standard (CP) acrylic which provides some UV protection, and archival (UF-5 or OP-3) acrylic which provides approximately 99% UV protection. We use only the highest quality acrylic with acrylic thickness ranging from 1/8 (3.2 mm) to 1/4" (6.4 mm) while many competitors use lower quality acrylic as thin as 2 mm. When viewing one of our cases, you will notice that every edge (including internal edges) is polished to a clear, glossy sheen using a high heat hydrogen-oxygen flame. The bending angles we use help to better light any item within one of our cases. These are just a few of the differences which clearly identify any CGA case as the worlds front runner in both quality and durability. We can create virtually any custom style or size case, and will gladly create fixed price listings for these or for larger quantities of in-stock cases at discounted prices.
