Do the artifact tokens just unlock or redeem too?

Dumb question and once it’s answered, you can delete this thread, but once I get Wand of Watoomb (or Orb or Eye) token, does that token give me one of the prizes in the vault or does it allow me to open the vault and therefore purchase tokens? Because I don’t have enough HP and don’t want to waste an artifact to unlock the vault. But if it redeems a prize in the vault, I’ll go ahead and open the token in case I get the Strange or Cyclops cover. Thanks!

It gives you a free pull in the matching vault.

All 3 vaults are visible, but locked. The token unlocks that specific vault and you are credited one pull. You can then purchase after that.
