So, this 77 × 22 × 22 mm electronic device got send to me in a box with the dimensions 153 × 78 × 60 mm which came in a parcel of 330 × 290 × 115 mm.
The parcel is 295 times the size of the item.
The box is 19 times the item. And filled with foam, because that’s what you do with all that air.
The parcel is 15 times the box.
I recognize some protection is needed, but this feels super excessive. Just put the box into an envelope. It’ll be fine.
