Swanstone or Veritek?

I purchased a Swanstone SS-3454 shower base from Lowes. However, the box was open and the material feels more like shiny plastic rather than the Swanstone samples. How can I confirm that it is Swanstone and not Veritek?
Thank You

The swanstone shower base I bought is thick and very solid and will not bend or flex anywhere. Even the front skirt part that doesn't have much support did not move. The Veritek shower base I saw at lowes, if I remember correctly, was kind of like a plastic basement sink kind of material that you could flex some.

No stickers or product numbers on it?
