There may be tears, holes, dirt, scratches, and fading in the parachute fabric; this is due to the fact that it is vintage, pre-used fabric. There will also be individual differences in color and texture. Any defects will not impact the function of the bag, as it has been covered with vinyl for protection and durability.
Note that vinyl parts soften and become sticky at high temperatures, or harden and crack at extreme low temperatures.
Due to using different parts of the parachute for each bag, they will all look slightly different. The design of the fabric for the bag you receive may not look identical to product photos.
