I have stored this item in a dark place after opening it. From a casual inspection, I don't see any white spots. I plan to package it as follows: Top and bottom sleeves -> Cardboard reinforcement on one side -> OPP bag -> Mini Letter If you would like reinforcement on both sides or packaging in a hard case, please comment before purchasing. Please comment if you have any questions or would like more details on the condition. -Search terms- Pokemon Card, Pokemon Card Game, Pokémon Trading Card Game, Eeveelutions, RRR, SAR, Tri-Rare, Triple Rare, Art Rare
