16-Bottle Essential Oil Carrying Case is perfect for 5ml (milliliter) bottles and will accomodate 15ml (1/2 ounce) bottles as well, up to 2 7/8" high and 1 3/16" diameter, so it's great for holding a mix of both sizes. If you use mostly 15ml, however, then you may want to get the 4-inch high case as it zips shut better with that size of bottle.
