First off - I agree with a negative review in part - you'll want the blue envelopes over the yellow envelopes since you might be able to see in the yellows (I haven't seen that trick but makes sense).

I have the blue version and it works great.

It's a hair pricey - but you're paying to reward a smart magician for their innovation and also to get a mind baffling trick into your show that you can do over and over.

At one point the instructions mention something about using a cheap soft glue - I would only say that I'm a hobbyist not a pro and I've done this without using that at all. With just a hair's worth of attention to detail and relatively little slight of hand I don't think you need any sort of glue - so you might want to try it that way first.

It's a smart trick - if you're creative you can add to it - if not - just watch the video above for the way to present it.

As the envelopes arrive blank - you can write whatever you want on them - which right out of the box puts you in a creative state. Or again - you can watch the video and the trick exactly as he did.

Either way - you'll wow small groups and large alike - so - watch the video and believe the hype. This is an easy trick that packs a heck of a punch.

This is a great effect but I deducted 1 star because I think it makes more sense to spend a little extra to get John Archer's "Further Education" DVD set. It's not that much more than this single effect and includes some other fine effects in addition to this one. The 2-DVD set doesn't include the envelopes, but you can find them online. Also, the DVD set includes a PDF with detailed instructions on how to prepare everything for "Blank Night."

Not hard to do. But needs good delivery. Watch Johns delivery and see what you think. It suits me.

This classic trick just took a giant leap in impossibility for our sophisticated audiences! The instruction book also includes some other themes to use for presentations. The only small drawback, is getting your empty envelopes back.
Thanks John Archer!

Thanks John for releasing this wonderful version of a classic bank night effect. For the money, this is a terrific value, The handling is clean and clever enough to fool Penn & Teller so, it will fool your audiences too! A lot of people have been concerned with getting replacement envelopes. Once you see the gaff and set-up this really should not pose a problem to any performer with a bit of ingenuity. Well worth the investment!

I have the DVD that includes this, without the pre-made props. It is possibly one of the best routines around. john Archer is simply one of the best and this is one of his best routines. Highly recommended

The handling of the trick will take a little practice.
Like many tricks, this one is all about presentation. I have found some other people performing this with the words on the envelopes changed and they are not great. So finding an original way to present may be hard.

Still worth every penny.

Great Effect! Kills audiences and really keeps them engaged. Take a little extra effort but worth it for the clean bill production. Would like to be provided a link or template for making restock envelopes though. Have to make your own template/find a stationary store to restock.

This trick is incredible I'm so happy I got this it's a real gem, the instruction are clear and one tip is one ce you begin to understand the trick watch his performance to see how and when he does certain things but honestly this trick is amazing and am very glad I bought this
