I was not expecting superior quality from the standard version of he product, but my Box has
2 manufacturing problems, which I consider as serious.
First, chains are a little bit
short, so when the box is located on a horizontal flat surface, it's cover doesn't remain open and
falls by itself.
Second, one of two enclosed cards has a piece of sand or mote between
layers, causing a perceptible bump on the card. When such a card is in the middle of desk, it is
causing a huge suspicious break.
I had contacted Mr. Joao two weeks ago, February 18 and
sent photo and video of these defects.
Till now, I have no solution.
UPDATE: I had got an advice about the chain, but still can't try to fix it as I am traveling.
The card was offered to be replaced at my own count.
The good news are, that it seems, that the box will work with any kind of tags, so you can experiment and create any props you may need for your performance.
