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 5/8' high and 1 1/8' 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. The 3-incher shown here will， however， hold 16 of all 15ml bottles and zip shut， but it is a tight fit. Case measures 5' wide x 5' deep x 3' tall. Color: Lavender exterior / Aqua Green interior. NOTE: Bottles are not included -- image shown is for example only.
