I apologise beforehand for my use of pictures in this thread. I'm not used to forums and didn't resize.
I finally figured out a great way to sleeve my monster tokens. I use 35x35mm coin envelopes, you know those clear plastic things that coin collectors use.
They fit very snuggly and have a little flap that keeps the monster from falling out when randomizing your bag.
They can probably be found in your local coin colletion supplies store. Or eBay, try "coin envelope 35mm" or similar string.
And then the stands. I am unsure if this has been done before but colour me redundant…
I read a tip here on the forum about filing down the teeth on the stand but that left the invstigator without footing. So I took one of those soft thingies you put under the legs of a table (I have no idea what they are called in english but they have them at IKEA), cut it down a bit, shaved it some and then sticked it to one of the sides in the stand.
Your brave cardboard investigators will never be harmed again!
Hopes this is useful to someone.
