These are old cards from about 20 years ago, so there are signs of aging such as **"whitening," "scratches," and "minor imperfections."** Please refrain from purchasing if you are looking for cards for collection (mint condition). They should be fine for actual use in a deck. The price is set lower than the market value, considering the condition. Please check the images and only purchase if you are satisfied. I can add more photos upon request. I will respond within 24 hours of your comment, or within 2 business days at the latest. #PokemonCard #PokemonTCG #GymChallenge #Promo #Energy #BasicEnergy #SpecialEnergy #Mirror #ADV #PCG #SetSale #PokemonCard #PokemonTCG #EnergyCard #GymChallenge #Promo #MirrorFoil
