How much does it cost to return an item?

Excuse me, could you please clarify the return policy and associated costs for this product? I'm interested in understanding the specifics of the return process, such as whether there's a restocking fee or if the shipping costs for the return are borne by the customer. Additionally, I'd like to know if there's a time limit within which I can initiate a return and still be eligible for a full refund. It would be greatly appreciated if you could provide me with a clear and concise answer to these questions.
