Magic Tricks

I like the fact that they are Bicycle backs/faces. They are a bit shiny, but look like a normal deck.

However, the cards clump in small batches of 3-6 cards. I tried breaking them with lots of shuffles, faros, etc. including rubbing each card front & back on a felt surface to wear off whatever was causing them to stick/clump. But they are not much better.

Example would be doing a side steal from riffle peek, sometime one card will easily slide out and sometimes 3 or 4 together as a block. I have not encountered this in other plastic decks, so not sure what's up.
