Received this yesterday. A case that holds graded notes. Thanks to @Bucephalus for recommending it. It was every bit as good as he said and also better than I expected. It was purchased on eBay from a seller in China so I wasn't too sure what to expect, despite Bucephalus's review. I purchased the one for small size graded notes. The seller also has one for large size notes. EDIT: Those are PSA slabs I also put in inside the case.
These Vaultz boxes are great for graded notes. http://www.staples.com/Vaultz-Aluminum-Locking-Small-Storage-Box-Black/product_1274074
Think I have three graded notes. I would like to find something better to put them in then the cardboard envelope they reside in.
