I have some Steamworks and Lounge Trinkets and I would like to add them to my currencies but when I click on them there's no link for me to add them to my currencies... Is there another way to do this? Were they only usable/redeemable during the events? Am I thinking of completely different items?

Go to one of the shops (there are direct links in your currencies) and turn them in there.

Wonderful! Thank you,
