This looks exactly like the set I got from my local magic store, it took a bit of tweaking to make the covers slide easy, but after a lot of use, they never let me down. I also use Smuckers jars, that I emptied and then painted the inside, a little baby powder and some washers for weight , help the covers slide perfectly . And I gaffed a lunch box to produce the sandwich,

Can anyone tell me what black plastic bag they use? It is a scrunched up garbage bag?

Love this prop & routine!

I use Welch's jelly jars with a typical household black garbage bag stuffed inside each jar.

For a strawberry/raspberry jar large pieces of dark red cellophane would do it.

Thank you, owen

I have the wenk version with covers sticking, any one have a solution?
