Pistachio shells can be used as handicrafts to make vases and pen holders.

1. Required materials: nut shells, plastic bottles, 502 glue, fresh-keeping bags, transparent glue, lace, ribbons.

2. First put the plastic bag on the bottle, wrap it tightly, and fix it with transparent glue.

3. Starting from the bottom of the bottle, select nut shells of similar sizes (so that the finished product is balanced) and put them together one by one, and stick glue on the joints.

4. Make the bottom of the bottle and then the body, layer by layer until it reaches the required height.

5. Gently rotate the plastic bottle left and right. If the bottle and the shell are loose, slowly pull out the bottle and the shell pen holder will be formed.

6. Finally, tie the decorative lace and you’re done.
