Casedby Hyehwa is unmanned and open 24 hours, so you can drop in any time, which I loved ·ᴗ· It's good for when you're waiting for a table, or when the timing before a play is awkward and you have a little time to kill ·ᴗ·

Inside, there were all kinds of phone cases on display, and besides the machine for making your own case, there were lots of other decorating items too ·ᴗ·

What photo ratio should you prepare for a custom phone case?

Photo pre-edited to a 9:16 ratio for the case

For a custom case at Casedby Hyehwa, 9:16 is the perfect ratio for your photo. I have lots of photos of my pretty daughter from her modeling work, so I edited them in advance and brought them, haha. If you want to prepare ahead, you need to make them 9:16!

Before visiting, just in case, I made two versions, 4:5 and 9:16. The 4:5 photo left a gap at the top or bottom. The 9:16 one had the sides cut off a little but fit perfectly ·ᴗ·

In particular, I left the camera hole area of the photo empty, and the design came out fitting exactly. I loved it.

Making time and what's included

After paying on my phone, it showed 'In production', and after waiting about 2 minutes the case came out looking lovely!

When I made a custom case at Casedby Hyehwa, a camera protector cover came with it, which touched me! My iPhone's camera bump sticks out so I'd been using a lens protector, but the moment I switched cases, bye-bye to that, haha.

How do black-and-white and color turn out?

At Casedby Hyehwa, black-and-white looks pretty and color comes out vivid ·ᴗ· I'm not making a couple set, I'll be carrying it alone, so I designed both a color and a black-and-white version!

Personally I find color prettier, so these days I'm using the color case!
