An exclusive set of Detective Pikachu tins will be coming to Walfart stores on April 5th! They will feature either Mewtwo-GX or Charizard-GX.
Each tin includes one of the two promos, four Detective Pikachu packs, two Sun & Moon series packs, and a PTCGO code card.
The two GX are already going to release in the Detective Pikachu case files on April 5th wherever Pokemon TCG products are sold. But if you want them in tin form instead, you now buy these from Walmart as an option!
These tins were not announced before because they are exclusive to Walmart stores. Thus, distributors did not post information about them since Pokemon is dealing directly with Walmart.
