Aquaring Mask Pack

It's a product you probably know. It's the Mediheal Aqua Ring. I noticed it had "ex rex ×2 ×3" written on the back.

I'm not entirely sure, but I think the difference might be the seller or the ingredient content. The product sold offline had "rex" written on it, while the one purchased online had "ex" written on it. Of course, I remember the rex product being much more expensive.

I didn't notice a big difference in the feel of the Rex Ex, so I bought this online at a special price and have been using it. You can definitely feel the moisture when you use it.
