We strongly believe that this black cardboard tube box for 30ml essential oil packaging can be a great choice for cosmetic businessmen to boost the sales of their goods. Small sized as it is this tube box uses 350g pure white cardboard (universal white in color) that is at the same time robust and esthetic to form the structure and 157g chrome paper compressed on the surface to realize the printing, black background printed on the chrome paper along with white fonts. The inner tube of this box has reversed edge to get a smooth touching, facilitating the usage of the box as well as the essential oil inside. There is no EVA or other stuffing inside the box as it can already ensure a good protection so need to make some economy with compact space usage. But if you want there is still possibility to do any customization to this black tube box for essential box as you need.
