The product uses gypsum/polyethylene/plastic/environment- friendly pigment with stable properties.

Under normal circumstances, there will be no discoloration.

Because it' s a brand new product that uses pigment coloring and is shipped sealed in small boxes.

So there will be a slight smell.

Thanks for your understanding.

After washing and ventilating with warm water, the smell will disappear in a short time.
