Dongdaemun Bolkku Guide: Make Your Own Pen at Seoul's Craft Parts Market, the City's Trendiest Hands-On Hobby

Ask what the trendiest hands-on hobby in Seoul is right now and the answer is bolkku, short for the Korean words for "pen decorating." You thread beads and charms onto a clear pen barrel until the ballpoint in your hand is one of a kind. The mecca of the craze, the accessory-parts wholesale floors of Dongdaemun Jonghap Market, draws serious crowds even on weekdays. Here is a first-timer's rundown of where to go, what to buy, and how to put it all together.

Why is bolkku suddenly everywhere?

Korea has a whole lineage of decorating culture, and it comes with its own vocabulary. The Korean word for decorating gets clipped and attached to whatever object is currently being dressed up: dakku is diary decorating, bakku is bag decorating with keyrings and charms, sinkku is shoe decorating. Bolkku, pen decorating, is the newest branch on that family tree. The formula works because a pen is small, practical, and personal. You compress your entire taste into an object you will actually hold every day, which keeps the barrier to entry low and the payoff constant.

The trend started among Gen Z women, then spread to elementary schoolers, their parents, and now travelers. The habit of posting finished pens on social media poured fuel on the fire, and the source of all those parts, Dongdaemun's craft-supply market, has become a place that fills up on weekdays as well as weekends.

The mecca: Dongdaemun Jonghap Market's parts floors

The home base of bolkku is Dongdaemun Jonghap Market. It is Seoul's wholesale mecca for fabric and accessory parts, and the shops selling beads, charms, ribbon, and small findings fill a whole floor of the building. The variety is on a different plane from any retail stationery shop, and because these are wholesale vendors, the prices are kind too.

Getting there is easy: it is a short walk from Dongdaemun Station on subway Lines 1 and 4. Step inside and the fabric section greets you first. Don't let it throw you; head up to the accessory-parts floor and a sea of beads opens out in every direction.

What you need, and how to choose it

The basic kit is refreshingly simple: one clear pen barrel with an ink cartridge inside, plus whatever beads and charms will decorate it. The barrel itself is easy to find in the parts market or at a stationery shop nearby. Everything after that is a matter of taste.

A few tricks make the choosing easier. Settle on a palette of two or three colors before you start, and the finished pen will look pulled together instead of chaotic. One statement charm backed by smaller supporting beads is the arrangement that rarely fails. And because parts are sold by the piece, resist the urge to hoard: buy just enough for a single pen. You will be back anyway.

How to make one: 30 minutes is plenty

1. Pull the ink cartridge out of the pen barrel.
2. Thread your beads and charms on in order. Shuffling the arrangement until the balance feels right is half the fun.
3. Slide the cartridge back in and tighten the end fitting.
4. Give the pen a shake. If anything rattles, recheck that end fitting.

If assembly feels intimidating, some shops will help you put the pen together, and studios nearby run one-day classes, so keep an eye out. The whole process works by pointing and picking, so you can manage without a word of Korean, and plenty of vendors will show you the price on a calculator.

A feel for the budget

The lovely thing about bolkku is how flexible the budget is. A basic barrel and a few kinds of beads get you started at a very comfortable price, and the total climbs only as you pile on metal charms or specialty parts. By travel-souvenir standards, even several pens leave your wallet only lightly bruised, which is why plenty of travelers make a whole batch as gifts for friends back home. Carry some small cash and those piece-by-piece payments go much faster.

Bundle it into a full Seoul day

Dongdaemun is too good a neighborhood to leave after a single activity. The natural flow goes like this: pick your parts in the market, assemble your pen nearby, then walk over toward Dongdaemun Design Plaza (DDP) for the night views. In the evening, cross to Gwangjang Market and close things out with bindaetteok (mung-bean pancakes) and mayak gimbap (bite-size seaweed rice rolls), and you have a properly full Seoul day.

It also pairs beautifully with the city's other current obsessions. Spend the morning on an Olive Young shopping run in Myeongdong, do bolkku in Dongdaemun in the afternoon, then head to Hongdae in the evening to squeeze into a four-cut photo booth, and you have cleared the trifecta of current Seoul trends in a single day.

An eye for parts: combination formulas that never fail

For beginners who freeze in front of the displays, there are formulas. First, one main charm plus two or three kinds of supporting beads; give a pen two protagonists and it turns noisy. Second, unify your metal tone. Commit to gold or commit to silver across all the fittings and the finish level jumps instantly. Third, slip clear or translucent beads between the colored ones so the colors have room to breathe. Finally, remember that a pen is ultimately something you hold: keep chunky parts away from the grip section and it will still be comfortable when you actually write with it.

Greed sneaks up on you as you browse, but a single pen holds fewer parts than you think. The leftovers graduate into keyrings and phone straps anyway, so planning your second project from the start is a perfectly legitimate strategy.

A quiet flow state, alone or together

The unexpected charm of bolkku is the immersion. While you sort through parts and shuffle arrangements, time simply disappears. For solo travelers it turns into something like meditation, oddly calming in the middle of the market noise. For couples and groups of friends, the popular format is making pens for each other and swapping at the end. The parts your companion picks quietly reveal their taste, and that is the hidden fun of the game.

A souvenir that never fights your luggage

The finished pen is light, it does not break, and a flat pouch will swallow as many as you can make. It is not a liquid, so airport carry-on rules have nothing to say about it. Above all, it is the only one of its kind in the world. Back home, every time you reach for it on your desk, Seoul comes back with it.

A spoonful of market etiquette

The parts floors are a workplace before they are a tourist attraction. The basics: do not jumble the displayed parts, and return whatever you touch to its place. If a vendor is in the middle of serving a wholesale customer, wait a beat before asking your question, and a quick word of permission before photographing a stall softens the mood considerably. These small courtesies have a way of coming back to you when it is time to talk prices.

How to slot it into your Seoul itinerary

Bolkku takes half a day at most, which makes it easy to tuck between bigger plans. Type "plan a 4-night 5-day Seoul trip with a Dongdaemun bolkku session" into Tripop and the AI arranges the Dongdaemun, Myeongdong, and Hongdae legs into a sensible route on its own. Whatever you spend on parts goes into the foreign-currency expense tracker with the exchange rate applied, and your saved itinerary opens offline even in the market's basement levels or anywhere the signal runs thin.
