The materials used to make the environmentally-friendly pen container include: used or expired bank cards, a thick cardboard (I used the cover of an old desk calendar) and transparent adhesive.

1. Stick three cards into a triangular prism with transparent glue;

2. repeat step 1, and all the waste cards need to be made into one * * * six triangular prisms with the same size;

3. Combine all six triangular prisms glued by cards into a large hexagonal prism with transparent glue;

4. Put the hexagonal prism just made on the desk calendar, draw the outline of the bottom required by the pen container, and pay attention to the margin of the hem;

5. Cut out the bottom of the hexagonal prism from the desk calendar with scissors and fold the six sides;

6. Glue the hexagonal prism and the bottom with transparent glue, and be careful not to make the pattern on the card upside down;

7. Because beautiful patterns are printed on bank cards and savings cards, this environmentally-friendly pen holder is very beautiful without additional decoration. Put all kinds of stationery to be stored.
