My post above is incorrect and I am unable to edit it. Mazza is not who I mean to refer to regarding the polybagged or taped shut business.

As far as what he told you about any difference in the plastic between the so-called Henning version and the so-called regular version of Tunnel of Darkness, unless you have held up at least 50 of random pieces of each version and compared them, you can't make a statement like that. Also, Tenyo didn't just do one run of Tunnel of Darkness: they had numerous factory runs. There are variations within the factory runs. The whole thing is silly.

I have an unopened DH Wonder Window. Anyone interested in trading for it?

Guys there is a fully packaged Tenyo wonder Window on that famous auction site,with original instruction manual as well.. bit expensive though as a Buy now imo MM.

Promotion without declaration gotta love that.

I believe the price of the Wonder Window being offered would be actually quite reasonable if it were BNIP... . It wouldn't be the deal of a lifetime of course, but nonetheless affordable.
(-) The problem is it has scratches which can reveal the secret.
(+) On the positive side, the seller sais it works great. Most Wonder Windows work great, but there are a few that won't work fluently ... . A lot has been said about this. And before someone jumps onto this and sais 'you have to follow the instructions exactly' (and of course they are right, especially with this trick) some Wonder Windows just DO NOT work fluently - there is something with the 'catching' mechanism. I know what I'm talking about because I've owned about 8 of these tricks a few years ago and tested 6 of them, carefully following the instructions!

I've only had 50/50 success with Wonder Windows. Half of the ones I've had don't work, and that includes some new out of the package.
