thermal label roll core,

There are 2 types: the first has an inner diameter of 10, an outer diameter of 12, and a length of 30. The second type has an inner diameter of 12.5, an outer diameter of 15, and a length of 39. All units are in mm. It is suitable for splitting thermal label paper rolls 30-50mm wide. The original purpose of the design was for portable thermal label printers that use small rolls of thermal labels. Small rolls are much more expensive, while large rolls are cheaper on Taobao. Since they need to be divided into small rolls after purchase, this core was designed. Using a hand drill or electric screwdriver to insert something and roll will save a lot of manual labor.
