This holds 15 batteries in 18650/20700/21700 and also has a storage area on either end.(((((Attention))))) due to the nature of 3D printing there may be artifacts or blemishes on the surface of items and these items can be sanded down very easily if you choose to do so....
Mine arrived a couple of days after ordering. It was packaged great to eliminate any damage during shipping and most importantly it is thick and sturdy. Standup 3D will be getting more of my business in the future.
