Mine have arrived too! Actually they arrived yesterday when I was at work, so I had to go pick them up at the post office this morning and spent the entire day at work staring at the package, itching to open it when I got home!
The tuck boxes are amazing! They are so much more "solid" and sturdy feeling that the USPCC tucks I'm used to, even the higher end custom ones with matte card and embossing... So yeah, feel awesome in the hand, and the level of detail in terms of the design and embossing is amazing too, so they are great for the eyes too!
One relatively minor bonus, but I still think it's cool, is that the brick I ordered came in a nice, solid brick box - the kind that JP actually sells separately. It doesn't look anything fancy, but it protects your decks a whole lot better than the usual flimsy ones you get straight from the producers... So...thanks for the free perk!
