These tees are "slightly imperfect". They have a small flaw that has not passed our high standard to sell at full price. Flaws may include a screen printing mark of small faint line (1cm long), a small speck of faded paint during the printing process. These are very small faults and do not effect the wear of the tees. Refunds or exchanges cannot be offered due to any of these faults or selecting the wrong size as there are only a handful of these.
