Hello Suhrob, my policy in all product descriptions & terms at checkout state that all sales are final. Meaning no returns are accepted due to not liking the product or changing your mind, etc. This is because I am a small business & with high demand, I do not have the time or capacity to handle returns due to those reasons, which is why I have it stated everywhere as much as possible.
However, if there are any defects etc, I will definitely make sure replacements are sent. if you had a quality issue, please let me know.
