Where do I get the reward?

I bought my first reward yesterday, 5$ for Steam wallet. It said it would be delivered within 24h, where can I pick up the reward when it's ready for pick up?

It will show up in your inventory where you have runes chest under the reward section click on the reward you got and the key will be there after they tell you it's ready to take

oh and don't hope that it will show in such a short time it may take up to a month if not a littel more
