The contents do look disturbed and not as if they were ready for shipping. Most companies I know that properly package things bubble wrap it to hell and back and then tape the bubble wrap closed. Looks like in picture 3 that the bottom left corner of the bubble wrap seems to be torn a bit.
TWM also comes with bearing their mark as all authentic products do. I have found a couple picture of how TWM packages and secures things.
I would definitely call TWM, here is their website link:
Short Shifters | TWM Performance Short Shifter Store
Edit: Open up my 2nd picture and look at your 4th and 5th picture. The bottom circle is smaller on the picture in mine compared to yours. Also there is no washer at the top on a TWM shifter. It looks like someone has opened the package and replaced the TWM product with some other off brand.
