Card Guardian - 9 Pocket Premium+ Binder with Zipper for 504 Cards - Side Loading Pockets for Trading Card Games TCG (Red)

Tough wallets for great safety

Great item, binding is a little stiff so you have to break in when new, but worked great so far

I love this brand, I've got a red and black version. Only complaint I have is I wish they made larger versions with the same style

Perfect for my nine year old grandsons and their baseball cards collections. They were so excited to receive these.

Overall, this binder has great build and is priced really well for what it is. The only issue I have is the same as others have pointed out, which is the width of the spine. Realistically this binder will only hold around 400 cards safely and at a capacity of 400, you have to be a bit mindful of readjusting the pages to sit flat when you're flipping through and one side starts becoming a big stack of pages. When closing the binder you also have to make sure you adjust pages so the page stack is as flat as possible.Capacity:I opened two romance dawn booster boxes and was able to fill the binder minus 4-6 pages, using 4 card slots for commons and rares, two slots for SR's and one slot for alternate arts. I double stacked a few of my rarer cards that I felt I should keep safe in the binder until I transfer the copies into a deck. I should also say that I threw a don card in each empty slot that wasn't filled to use as placeholder.So with that being said, when I close the binder, the fit is pretty damn tight, but I can tell that the pages are laying flat, with the only cards at risk being the cards closest to the spine. I would stick to the version of the binder with 360 card capacity. Man.... if this company can update this binder's spine width it would be an amazing binder and I would be purchasing another two in anticipation of the next two upcoming booster boxes.
