How to make white, translucent, glossy plastic

[B.Y.O.B.]

It doesn't seem right to me to make plastic objects with glass material.

My advice is to use what looks right. The shaders are not restricted to simulate only the real-world materials they were named after.
For example, in the real world many substances that look like glass are actually plastics, e.g. spectacles or camera lenses, and in LuxCore it would be correct to use the "glass" material for them.
Another example is water or other liquids: in Lux, you use the "glass" material, and that's the correct shader to use.

Thank you. You are completely right.
