With just a sheet of A4 paper, you can have a pure white photo background, which is the key to taking perfect and clear photos of objects.
（只需要搭配一张A4纸，你就能拥有一个纯白拍照背景板，这是拍出完美清晰的物品展示照的关键。）

There are two versions, one with a scale and one without a scale, the one with a scale makes it easy to align A4 paper, I really like neat items, and the one without a scale prints faster.

（有两个版本，分别是带刻度和不带刻度的，带刻度的可以方便对齐A4纸，我很喜欢整齐的物品，不带刻度的打印得更快。）
