Please note that we try to highlight any condition issues in the item description and photos. If you do not see a condition description in the photos, this means that we evaluated the auction lot, and we did not see any cracks, chips, or noteworthy flaws. However, we still request that you evaluate all of the photos too. While we are experts at spotting flaws, it is always possible to miss something during our analysis and curating process.
