This is a design made three years ago. The idea at that time was to define the semantics of this product according to the infusion bag: infusion is a cure for the body, and charging treasure is also a cure for the mobile phone (cure the anxiety about the battery life of the mobile phone). Also do not need much capacity, so thin is the first choice. Moreover, it also takes the characteristic that infusion bags can be "hung". This characteristic of charging treasure can also meet the needs of different situations. Hanging bags/charging can be hung on high-speed buses, etc.
The texture is taken from the irregular filling of logo letters, and the process can be used for UV light and mold concave engraving, with full details.
