When you choose the ball, you do not know which size to choose.
The 6cm ball is the excellent choice, whether the size, weight or softness are the most suitable for little children. The size is large enough that children cannot swallow. Considering the shipping cost, the 6 cm ball is also very advantageous in terms of price which can have more than 300,000pcs per 40HQ, and it is the most popular size at home and abroad.
If your plastic ball is used in large amusement facilities or amusement parks, we suggest you choose 8cm ball, because 8cm ball is very economical. When you hear this suggestion, you may not think so. You may refute that the unit price of 8cm balls is much higher than 6cm balls. Let me give an example to explain. If a ball pool needs 5 cubic balls,It needs about 23000 pcs of 6cm balls, but it only needs about 10000 pcs of 8cm balls, the quantity of 6cm balls required is about 2.3 times that of 8cm balls, but compared with the price, the price of 8cm balls is less than 2.3 times that of 6cm balls. Of course, if it is only for family use, we still recommend the 6 cm ball
