DSM Pumas were $180 and came with a special box, rope laces, and leather dust bag.
Grand Openings were $180 and came a regular Asics box with an extra set of laces.
The quality of the materials on the DSM Pumas are certainly better when compared side by side. I will say that the leather on the Asics are better than a general release though. The craftsmanship is also better on the Pumas. The seam of the upper and the sole doesn't look too good on the Asics.
If you have to pay resale, go for the Pumas.
