Yoyofactory b-grade delrin wedge lack of markings

[Breadroid]

Just noticed that my b-grade delrin wedge doesn’t have the engravings on the hub that the standard production runs have. Is this something that are only on this particular b-grade? Besides the tiny b-grade stamp on the rims, this is an unmarked yoyo.

The snowflake winter edition didn’t come with any markings. Not just B-grades.

(The winter edition ones are white with a silver hub)

My B Grade markings are on the edge. I don’t think the production run had any markings.
