Returns
Stock is dynamic. It's not completely managed by us, as we're involved with several parties such as the factory and our storage. Therefore, the actual inventory could alter at any time. It is possible that stocks could be depleted after the order has been made.
The period of time is 30 days. If 30 days have gone in the past since you purchased, unfortunately we can't offer an exchange or refund.
In order to be eligible for a refund the item must be in good condition and in the same condition that you received it. It must also be in the original package.
