Are there any DIY materials that can be bought in Shenzhen? If it really doesn't work, you can go through customs.
There are some lace beads on the second and third floors of Shenzhen Dongmen Jinghua (Hotel) Fabric City (south of Mao Ye). East Gate, Le Tong Road and the Olympic Building. There is a new white horse clothing accessories city. The third and fourth floors seem to sell clothing accessories, such as imitation pearls, lace, sequins, wooden beads, ornaments and rhinestones. There is a big children's music and clothing accessories market diagonally opposite the new White Horse, which is also sold on the fourth and fifth floors. Go to the clothing accessories market and have a closer look. The variety of beads is dazzling. I hope you have what you need.
