If you wish to have an exchange because you have received a team which goes against your religious/political views, this can be done, however if not listed in teams you wish to avoid, you will be responsible for covering the cost of sending a new shirt out. 

Tight Fit

If you're looking to return the product because it's a tight fit and wish to have a refund, this will not be a problem however we will only refund the cost of your mystery box not your original postage or returning postage cost.
