As all of these products are bespoke it does mean they cannot be brought back into stock and resold if you change your mind. For this reason I would respectfully ask you to be sure all of the details are correct when you place an order.
I would never want any client to be unhappy with a purchase and therefore offer a full refund on all purchases. I do require any products purchased to be returned and the cost of return shipping to be covered by the buyer. In the (highly unlikely!) event that there is a problem with the quality of a product then I will also re-imburse the cost of return shipping.
