I'm sorry you don't like the quality of our card stock. We use industry standard playing card stock now, but we do realize that some people do have preferences for ultra premium types of card stock.
We're currently researching methods for creating linen textured decks and upgrading our standard card stock to black core casino grade card stock. It's difficult because the stocks that we want to use are made in France and the French provider wants us to buy an entire shipping container (50 tons) of the paper at once, which is a lot for a small company like ours. Not only for committing the money to such a huge volume of paper, but we then have to store it in a climate controlled facility until we're ready to use it.
It wasn't my intention to offend you but if you really want to know how to sell more decks or
how to make them more appealing then the card stock has to be considered when more
than one person is telling you that it's too thin and the boxes crush easily.
Ultra premium paper isn't required, just a card that will not bend or crease when shuffled and won't
show wear after 10 uses. No one expects French Linen paper but at least one that would hold up
to some use would make the decks more appealing.
Go grab one of your own decks. Shuffle it about 20 times and put it in and out of the box each
time. See what you think. You don't have to use it as a tarot deck. Play old maid, whatever.
See what you think about how it shuffles and how the cards hold up. Maybe some of us
received some decks that were unusually thin card stock.
