A different date idea in Hyehwa: Casedby Hyehwa

Casedby Hyehwa (케이스드바이 혜화) is a custom shop near Hyehwa Station where you can make your own phone case. I found it while looking for a different kind of date in Hyehwa🙂 Search for places to go or date ideas in Hyehwa these days and you mostly get cafés, plays and restaurants, but this place let us try something hands-on and leave with a memory, so it really appealed to me.

How late is Casedby Hyehwa open?

Casedby Hyehwa is an unmanned shop that runs 24 hours, so you can visit any time with no time limit. The location works well as a casual stop on a Daehak-ro date after dinner. The 24-hour unmanned operation was the first thing that caught my eye, and I thought it makes a great Hyehwa activity for couples who are out late.

The inside of the shop felt clean and tidy, and the machine and how to use it were intuitive, so even first-timers can manage without trouble.

Couple phone cases with an AI dog character

At Casedby Hyehwa, I used an AI-made cartoon version of our dog and made matching couple cases with my husband's. I wanted to make it a bit more special. The result was cuter and more polished than I expected, and my satisfaction shot up the moment I saw it, haha. Maybe because it was my first time making an item like this myself, it felt like more than just an object.

How long it takes from printing to finished case

The most impressive thing about Casedby Hyehwa was the speed. After I pressed the print button, I had the finished case in my hands in less than 3 minutes. There was almost no waiting, so being able to wrap up the whole experience in such a short time was another big plus.

Walking out with a case I'd made myself felt like taking the memory of that day with me, which made it more meaningful. Next time I plan to make another one with a different concept. Once you've made one, you keep wanting to try new designs. If you're looking for places to go in Hyehwa, I'd definitely recommend trying to make your own phone case at Casedby at least once!!
