My concerns is the time and effort to re package each item.
It’s worth it when packaging materially reduces returns and increases conversion, because those two levers usually pay back faster than “branding” alone.
Custom packaging makes sense if your item is fragile, scratches easily, tangles, or arrives looking cheap, or if customers buy it as a gift and packaging drives perceived value and reviews. A paper card insert is usually enough if the product already arrives protected and your main goal is simple branding, care instructions, and support contact details.
If you’re very early and still validating demand, start with a clean protective baseline plus a high-quality insert, then upgrade once you see stable sales and you know your return reasons.
Also consider Amazon compliance and customer sentiment: avoid inserts that ask for reviews, incentives, or off-Amazon contact in a way that looks like review manipulation, and focus the insert on care, sizing, and what to do if there’s an issue.
