Very impressed! Was nervous but it looks way more expensive then it really is. The engraving were perfec. It's an awesome knife, my boyfriend loves it! Fast shipping too!

Perfect for my vehicle storage needs, and no slip bottom makes it a lot easier driving around without it sliding back and forth like my old container. Strongly recommend it.

I have an iPhone 6s Plus in an Otterbox Defender case (the two layer type), and it fits! It takes a couple of times to figure out the best angle to insert the phone because of its large size, but it definitely fits. It's nice having easy access to my phone while riding.

Ex Output:

positive
