Friend flying in from China, what Chinese Pokémon exclusives are actually worth grabbing?

My mate is flying over from China soon and can bring back some sealed Chinese Pokémon exclusives from the Pokémon centre.

I’m trying to work out what’s actually worth grabbing from an investing/collector point of view rather than just buying random boxes

These are the main options -

• Chinese 151 Puzzle Fridge Magnet Set

• Eevee GX Gift Box - Vaporeon/Jolteon/Flareon

• 151 Original Partner Boutique Gift Boxes

• Umbreon Photo Frame Exhibition Gift Box

• Mew Photo Frame Exhibition Gift Box
