Delicious Ambitious: Difficult Card Magic

I was amazed at how easily the double lift and triple lift could be performed when I first purchased it. (Of course, some skill is required.)
I carefully stored it, but when I took it out recently, I found that all four cards were stuck together with their processed surfaces facing each other. The same thing happened to the spare set I had kept unopened (tears). I carefully peeled them apart, but the central part of the processed area was lifted up like a film and peeled off. (It may be difficult to see in the photo...)
Therefore, I have listed the item as with scratches and stains.
One side of the Phoenix red back and one side of the Bicycle blue back (which were not facing each other) are undamaged.

Despite this condition, the triple lift and other tricks are still possible, so I am listing it for sale. If you are careful about light reflection and other things, you should be able to perform the tricks without the audience noticing.
The four cards are the ones with the least damage to the processed surface from the two sets I own (two cards each).
The included DVD is in good working condition.

This is a defective item. Please understand the condition well and agree to no claims or returns.
