In the past I've been very happy with the thread included in The Million Dollar Knot, and with the Legacy Thread sold here. I like a little less, but have been happy with Mesika's invisible elastic Thread. This one is not in the same category.

First off, it's not regular invisible elastic thread. It's CLEAR invisible elastic thread. So, beware. You will have to use a sharpie if you want it to be dark.

Second, the one I got was not "super strong" as the add says. It was very weak, in fact.

I want to make sure that I tell you that this is a review of the thread exclusively because I brought up the issue to Penguin Magic and they dealt with it wonderfully. Top Nudge customer service as always. 5 stars to penguin. 2 stars to this thread.

I got this same thread from a different website but I would still like to suggest you never buy this I got two spools one got tangled and the other one broke like it never existed it could barely lift a card!, Penguin is a great website but this thread is not.
