Sometimes complaining works.
I posted how I did not like the size of the original DIY kits and someone listened.
I just got this new "SAMPLE" version in the mail today. Sorry for the crappy pictures.
First pic is the original with the new WAY better size DIY kit next to it.
Second pic is the new sized DIY kit in between a PSA and SGC slab for size comparison. The best part is it is so much thinner so you can store WAY more protected cards in the same area.
Third picture compares the new size to the old size and a SGC slab.
