I can help with OPC base and sp's , have heavy inventory from the last 3 years.
Working on a couple of sets, but need these to complete a set from 2020-21:
501, 509, 516, 519, 521, 527, 531, 533, 536, 546, 547, 550, 560, 568, 571, 572, 576, 581, 591.
This is set #1, so I can also use doubles for my second set.

Can use Flyers inserts, playing cards, Giroux platinum preview, etc. Paralels,
Have tons of retro, red, black, blue.

LMK
