Ooshirt.com does not typically offer physical samples of custom designs before an order is placed. However, they do provide a mock-up tool that allows customers to visualize how their designs will look on selected apparel items before making a purchase. This feature can be very helpful in ensuring that the design meets expectations. If you have any specific concerns about your design or require adjustments, Ooshirt encourages customers to utilize the mock-up tool for revisions. For further details about the ordering process or any other inquiries, it may be beneficial to check the relevant sections of their website, as they often have updated information and resources available.
