Paint the entire box, inside and out. Let it dry.

Press strips of washi tape vertically or horizontally across the outside of the box, covering it completely.

Use scissors to trim the ends of the tape at the edges of the box.

Paint two coats of decoupage medium over the box, then let it dry.

Apply three evenly spaced adhesive Velcro dots across the inside of the box flap, with their matches aligned below the serrated edge to close the box.

Slide the washi tape rolls onto the empty tube and store them inside the box. Pull the washi tape out and fold it over the serrated lip, so you can trim the tape as you dispense it.
