How to distinguish the quality of PVC fridge magnet products?

First look at the pvc fridge magnet raw and cooked. When the product comes out of the oven and cools, fold it a little, if it cracks it means it is not cooked.

Secondly, color and position. According to the customer's sample, we can see whether the color and location of the products we produce are consistent with the sample.

See if the bottom of the PVC refrigerator magnet is flat, and there should be no bubbles in the place where the magnet on the back of the product cannot be attached

Look at the quality of soft pvc fridge magnets again. It mainly depends on whether the product has bubbles, impurities and mixed colors.
