Looking for Kraft Box Packaging Ideas

I’m looking for some practical kraft box packaging ideas for a small product brand. I like the natural and simple look of kraft packaging, but I want the boxes to feel professional rather than plain.

I’m considering options like custom logos, one-color printing, simple patterns, and thank-you messages inside the box. I’m also wondering if adding a small window, custom inserts, or a unique folding style would make the packaging more appealing without making it too expensive.

For those who have used kraft boxes before, what designs or features worked well for you? Did you choose plain kraft boxes with stickers, fully printed boxes, or custom packaging?

I’d also appreciate suggestions on choosing the right box size and material, especially for products that need extra protection during shipping. Any ideas or experiences would be helpful.
