Don’t take this the wrong way but you aren’t very expert at searching the Internet either.
Prior to seeing the Walmart listing, I felt like you but I have a hunch Walmart isn’t likely
to offer a counterfeit TAOM chalk for $11. So my gut told me it was real but I also made
sure the chalk actually existed. Sure nuf, the chalk looks legit to me and was inexpensive.
The AI answer that they sell a dedicated snooker chalk shows you something that ISN’T V10 (it’s 2.0). The other listings call V10 pool snooker chalk (presumably to catch people searching for either one).
Hopefully you got the real deal.
