A spice rack itself is barely worth wrapping, but the jars inside are what cause a mess if a lid pops open in a box. Keep every jar upright and sealed and this is one of the quickest packs in the kitchen.
Pro tip: Snap a quick photo of the rack's spice arrangement so restocking it in the new kitchen takes seconds.
Watch out: Do not pack spice jars on their sides even briefly; a lid that seemed sealed can leak and stain everything below it.
