What is the Mark at the Bottom of the Ace Grading Slab?
The small mark found at the bottom of an Ace Grading slab is not damage or an error.
It is the injection port used during the manufacturing process and is an essential part of how our slabs are produced.
This feature ensures the strength and integrity of the slab — it is completely normal and found on all Ace slabs.
