21700 Batteries box

21700 Batteries BoxThis is a practical and compact storage box designed to safely hold 21700 batteries for electronic cigarettes.The model consists of two parts: the main body and a removable cap. For a secure closure, the design requires 4 circular magnets (Ø4 mm x 1.5 mm height) to be inserted in the dedicated slots. These magnets ensure the lid stays firmly in place while remaining easy to open when needed. I have personally been using this model for over 4 years, and it has proven to be practical, slim, and elegant — the perfect solution for everyday use.
