The reason why there are so few Sasseur brands in Wujiang is that the hand-made process of Sasseur is cumbersome and time-consuming, and there is no assembly line production.

According to relevant public information inquiries, Wujiang Sand Ship is a traditional and well-known brand that produces sand boxes, sand blocks, sand bricks and other traditional hand-made small toys and game props. Due to the production process and time-consuming issues, the quantity is limited.

Released in limited form, the brand's products are available in relatively small quantities.
