There is a USB flash disk made of pure wood. The patterns on it are divided into two kinds, one is Apollo, and the other is his sister, the goddess of the moon. The craftsmanship is very fine, it can be worn as a necklace. Unfortunately, it is relatively expensive, the 512MB USB disk is priced at 128 yuan. But it is quite meaningful as a souvenir. Friends who are interested can go and take a look.
