Please check for damage before opening. Thank you for looking and please let me know if you have any questions! International Buyers – Please Note. Other terms and conditions. We strive to be reasonable in the event of a disagreement and ask that buyers afford us the same level of fairness. As a grown adult, it is important that you take responsibility for your actions. Abiding to a contract and seeing through that contract is a demonstration of acting responsibly. Too many of you are children. I do not deal with children, or adults that behave like children. Don’t contact requesting me to loosen it. I do not respond to excessive messages. Items are pretty self explanatory and the rules of the game are simple. I have confidence in the third party grading companies and stand by their assessment for each of our the auctions. Professional grading is subjective and different 3rd party graders will often disagree over the grading on a single card. Such a disagreement is not a justifiable reason for a return. Raw cards offered for sale will generally grade as Near-Mint (PSA or BGS 7) grade or better. Raw cards are considered not gem mint.
