I'm a Luna pouch, inspired by moon shape and translated to a pouch. I have 6 built-in rubber slots for essential oil bottles and can be maximize to 8 bottles as it has extra room in the middle.
 
The pouch fits to standard size of essential oil bottles from 5ml, 10ml or 15ml.
 
The size of Luna Pouch is 15 x 6 x 14 cm
