as the title says. I redeemed my items but how do you actually get the items in game?

When you log in on the character you want them on you have to type /claim and that will allow you to get the items in game from what you claimed in the TCG

Also be sure to /claim them on the toon you want them on!!! They are NO-TRADE as soon as you claim it, so if it's a vendor let your crafter take it, etc.

Also if you claim it on the wrong toon SOE will not let you claim it on another toon, so try not to mess up
