Bumps on a Coach Purse

Those bumps look bumps from warble larvae. But that's usually on a living animal unless these were there originally. North American tanners wouldn't touch hides with warble marks.

To see if it's a knockoff, look inside the bag and see if there is a coach leather tag sewn inside the bag. It should have a description of the company, leather used, and a serial number. If not, then I would think it's a fake.

I was thinking that it may be heat.

I was thinking that it might be a knockoff too. I have a Coach bag (a gift) and it is very well constructed. I have accidentally spilled an entire beer (don't ask) inside it and it cleaned up like new.

Or, is it possible that it wasn't water that created that bubble? It almost looks as if it was exposed to something that had a chemical reaction--a cleaner or some other liquid? Or possibly a heat source of some kind?

Hard to believe plain water did that.

Is it possible that it is a knockoff and not the real thing?
