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.


Can you make a phone case without your own photos?
The machines at Casedby Hyehwa come with a wide range of default designs, so even without personal photos you can just pick one you like and get a pretty case. That was the best part for me: simply choosing a design gave a polished result. 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.



How does the phone case making process work?
Making a phone case at Casedby Hyehwa takes four steps: choosing a design, adjusting the image position, paying and printing. The instructions are laid out clearly, so anyone can follow them in order and make one easily.
- Choose a design
- Adjust the image position
- Pay
The steps are so simple that even people who aren't used to machines like this can follow along easily👍



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.


Case types and supported phones
At Casedby Hyehwa you can choose between a clear case and a MagSafe case. I went with MagSafe for practicality. I use MagSafe a lot these days, so I was happy with how useful it is as well as how it looks.

Many phone models are supported, including iPhone and Galaxy, so you can make a case for most phones without a problem. Just check your model before you go and it's even easier. My overall impression was that Casedby Hyehwa isn't just a place to buy a product but an interactive space where you can enjoy the experience of making it yourself.


Who is Casedby Hyehwa a good fit for?
Casedby Hyehwa suits a Hyehwa date really well, and I think it would also be a fun memory with friends, each making a case with their own personality. I think these people in particular will be very happy here.
- ✔ People who want to make couple items
- ✔ People who want a special design of their own
- ✔ People looking for a Daehak-ro date course
For anyone who values individuality in what they buy these days, this kind of custom-making experience should feel even more appealing💕

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!!
