Garbage, these don't close properly
Item Package Quantity: 2
These are defective. They don't close seal properly whatsoever. If you intend the handle the card, move it around at all, these will damage your nice cards. Do not buy if quality and protection is what you need.

Great Value - Use the right adhesive and they are crystal clear
Item Package Quantity: 48
These are generally pretty good. Some have rough edges from the mold, but there's not too many in the pack that are like that. Each come shipped in a bag. DO NOT USE GORILLA GLUE IMPACT TOUGH SUPER GLUE to seal these. They cloud the plastic. I used JB WELD LIGHT ACTIVATED and it worked perfectly. Model glue probably works too, but I haven't tried that yet. Less is more.

Great Cases for Cards
Item Package Quantity: 12, Item Package Quantity: 12
These were great for what I wanted them for. I like the look of having a card slabbed with a label but sending to the big grading companies is expensive. I was able to Slab wrestling cards, and sports cards. I even did one of my garbage pail kids. These are not designed to just snap together and do require some plastic adhesive or glue. Not a bad price for what I needed them for.

Don’t get this
Item Package Quantity: 6
The two sides don’t fit together properly and pop open with the slightest of uneven pressure. There’s practically no clips to keep them together so cards just slide right out of them when picked up vertically. Don’t get this if you are looking for something to keep very expensive items in as they will just get ruined or lost. You get what you pay for.
