Do me a favor, master. The Cantonese pronunciation of the word "open margin note" helps me to think about which English word refers to a material. Thank you.

Kaibianzhu's name does not come from English or other foreign languages, but from the way it gets its raw materials.

Open-edged beaded skin, also known as coated skin, is made by throwing it in half along the backs of pigs and cows (this process is called open-edged), trimming the loose first or second open-edged skin of abdomen and limbs, and sticking various PVC films of solid color, metallic color, bright pearl color, magic color or multicolor on its surface.

Open-edged pearl skin is a smooth box skin in English.
