When will Pop Mart start making TCG? I think this is a strategic issue!

The key is that it overlaps highly with the original user base, and it can also take a share of Pokémon and One Piece. Why not do it?
Cards are more addictive than blind box figures, and they solve the consumption problem. The profit margin will only be higher, not lower.
People don't casually throw away figures after buying them, but with cards, aside from a few top-tier cards, the rest are consumables that end up in the trash.
