TOP is the graded card protection division of Gstar Technology (Shenzhen) Ltd — a vertically integrated OEM & ODM manufacturer founded in 2012, headquartered in Shenzhen, China. We design and manufacture protective products for professionally graded trading cards: graded card protectors, guards, slab protectors, and slab bumpers, in TPU, silicone, acrylic, and metal.
Why Graded Card Protection
A graded slab protects the card inside, but the slab itself is exposed to scratches, edge impact, UV light, and handling damage during storage, display, and shipping. Grading companies each use their own slab profile — PSA, BGS, CGC, and SGC cases differ in dimensions and edge geometry — which is why protection has to be designed around the slab, not copied from one size to another.
That is the problem TOP is built to solve. We combine four materials — TPU, silicone, acrylic, and metal — with precision tooling to produce protectors, guards, bumpers, and cases that fit each grading slab type the way it is actually used by collectors, card shops, and shippers.
