## Customer Reviews

### ⭐⭐⭐⭐⭐ Preliminary review
*by B***N on November 28, 2024*

Not a full review but just some things i've noticed that some people will want to know about.-It is thick and heavier than expected. Definitely not something you want to carry around but i like that it feels so substantial.-The included punch is unreliable. Doesn't always spring actuate. 50% success rate-Even though it's made out of steel, it's not very magnetic. If you put your average fridge magnet on it, it will barely stay on. If you use a rare earth magnetic, it will stick better but is still very weak. So if you're thinking of hiding this wallet somewhere using a magnet, then this is not the wallet to get.

### ⭐⭐⭐⭐ Good plates, bad punch
*by T***Y on August 20, 2025*

Nice concept and quality steel plates. The punch is a problem. It worked well for the first few words but then failed. I found unscrewing the different components and then applying very slow, steady pressure helped it to work better, though I had to do that several times throughout the process. I suspect the failure has to do with a misalignment of the internal piston. So, be patient with the punch or have another punch to use to mark the plates.

### ⭐ Disappointed in product quality. Punch pin is defective.
*by C***E on February 24, 2025*

The punch pin to mark the cards does not function. Ordered a replacement and the punch pin was also defective. Had to borrow a friends to mark y cards. Very Disappointing. You would think Keystone would sell a better product than this.
