This is what Alvo posted at the Café...
"Marc,
The Postmentalism package comes with one gimmick. I also throw in a free refill just in case anything happens during shipping, etc. The gimmick should last a long time. But in case it gets lost or damaged, I will be releasing a replacement kit for those who own Postmentalism.
Alvo"
I had a quick look around, and I couldn't find anything for you (doesn't mean it doesn't exist, though), so the best thing to do is probably to sign up at the Café, if you don't already have an account there, and PM Alvo himself, he should sort that out for you.
