I used hot glue for this but you can use Red Liner tape too. Glue to form a cylinder.
Pinch one side like so
It will look like this inside
Using a paper crimper, crimp about 1/2 inch. This will make it looked sealed like the sour cream containers you would get at a fast food joint.
Hot glue the side you crimped. Now place candies or any prize or treat you would like in the container.
Add a little tag or note and you are done!
