>>36650691That kind of binder is fine since it has card slots with a back, and it's also Ultra Pro which is a common brand but still good enough. For sleeving good cards or cards you like, make sure to pick up actual sleeves usually sold in packets of 50 or 60 and not the packet of 100 flimsy sleeves. You can also pick up a 100 flimsy packet or two though if you have other cards you want protected but don't want to use good sleeves since good sleeves can get expensive over time. Commons (circle symbol) and Uncommons (diamond symbol) can remain unsleeved. Some exceptions to this right now are Cynthia from Ultra Prism and Guzma from Burning Shadows which go for around $7 and $5 USD as non-reverses rares. Non-Holo Rares (star symbol) and Reverse Rares (shiny cards that look like OP's top right Litten and can be any of the three non-holo rarities mentioned) can be stored in flimsy sleeves since you'll be getting one in every pack but they generally are not worth much if anything at all.
