What is Casedby in Seongsu?

Casedby is a place in Seongsu where you can make a phone case with exactly the design you want, on the spot. Did you all know a place like this exists in Seongsu?? I always thought you had to order online to get a custom design, but at Casedby you just enter your image and the case is made right there.

Casedby isn't far from Seongsu Station, so we got off at the station and walked. Seongsu on a weekend is seriously insane, the crowds,,

It would be great to visit when you want to make special cases with friends, family or your partner! And it's perfect as a date course too!

Casedby case types and prices

There are 2 types of cases at Casedby: MagSafe and clear.

  • MagSafe - ₩28,700
  • Clear case - ₩22,800

The clear one definitely looks whiter and cleaner, which is more my style, but I can't give up MagSafe,, so my boyfriend and I went with MagSafe!

Do you need to make the case design in advance?

Yes, it's best to make your design before you go to Casedby. Inside the shop, examples of cases are lined up everywhere, but that's really only a small part, and you can customize anything you like, which is great. I thought I'd just go and look at designs there! and ended up standing for 30-40 minutes making my design, hahaha

Making the case isn't hard at all. You just click as instructed. If you prepare the design beforehand, 90% of the work is done! Definitely make your design in advance! (I used Canva to make one from our couple photos.)

How to make a phone case at Casedby

Scan the QR code shown in front of the Casedby machine and a screen appears on your phone where you can pick your image. Enter it there and you're done! You can also add text and decorate the image.

There are also lots of keyrings and charms for decorating your phone after you make the case, so if you want, you can dress up your phone too.

On the screen from the QR code, choose your phone model and upload the image! They can make cases even for fairly old models!

Done in 1 minute at the case vending machine

Once you confirm, ta-da, the case drops right out, haha. A case vending machine, my first time seeing one,, the world has gotten so good.

After payment, it takes about 1 minute..? Something like that? It comes out super fast. You can watch the progress on the vending machine and it was so cute haha.

Couple MagSafe cases from travel photos: how did they turn out?

There's a bench near Casedby, so we sat down and put the finished cases on right away haha. I used to use a plain clear MagSafe case, and I could really feel how much the mood changes just by switching the phone case!

What do you think of our cases? Cute, right? I spent some time picking images in a rush, but I loved the finished result so much that I was in a great mood. Since it's MagSafe, a card wallet attaches to the back too!

I highly recommend it as a Seongsu date course. When I was leaving, groups of friends were making cases too! We made couple cases from photos of our travel memories, and it was nice to look through photos together for the first time in a while to pick one and bring back memories, then see it every day on the case. Two birds, one stone!

If kids have phones, I think it would also be fun for a family to come, pick images and make cases for each other~!

A one-day Seongsu date course

Have lunch in Seongsu, wander around the pop-up stores, make couple cases at Casedby, then have a drink at a nice bar in the evening, and the weekend just flies by! If you know any fun, unusual date spots in Seongsu, tell me in the comments!! I'm getting a bit tired of the same old dates lately!!

Bonus: riding Ttareungi to see tulips from Seongsu

Oh, and the tulips are so pretty these days. I heard Seoulsup is under construction, so we rode a Ttareungi (Seoul public bike) from Seongsu toward the Han River to Yongbi Park, and it was so pretty and lovely! Go take photos before the tulips wilt~
