The gauges are 45.65.85.105. I don't think there are any particular problems, but please refrain from purchasing if you are very concerned, as there may be minor scratches, stains, or crushed boxes on the package to the extent that they do not affect the contents, as they may have been present since the time of purchase. I handle the item with care after storing it at home.
