You choose: hinged or stacking! This all wood oil box comes with a customizable oil grid that holds up to 36 essential oils bottles (5mL or 15mL). Cross pieces can be removed from the grid making space for taller 10mL roller bottles. Choosing a hinged lid will turn this box into a traditional oil storage solution. However, you can also choose to have this lid stackable. Nest the oil box into the lid where you’ll have room to tuck away your cap stickers, capsules, blending supplies, or anything else you’d like to use regularly without having to clutter your counter.
