Do you state no return if the hygiene strip is removed? That seems acceptable, even expected. Commercial firms as policy don't accept such returns and some, like Next, don't allow returns at all unless the item's faulty, to reassure buyers about hygiene (as policy only, as there's no law or regulation prohibiting such returns).
If you state that you don't accept returns if the hygiene strip is removed, it might assure a potential buyer that the hygiene strip would be intact. Though it's be hard how you as seller can be certain a buyer returning it hasn't removed it before you receive it back to check it for yourself. Are you able to state no returns at all, unless faulty?
