The Project
You’ve seen those tiny, addictive blind bags at the store—the ones that cost a small fortune for a random trinket. But what if you could make your own, customized for a Kpop Demon Hunter theme, and even turn it into an ASMR unboxing experience? That’s exactly what this paper DIY project delivers: a set of Ramen-themed blind bags featuring characters Rumi, Mira, and Zoey.
This isn’t just about saving money—though you will—it’s about crafting a personalized unboxing experience that feels authentic and satisfying. The transformation is simple: you take printable templates, some basic paper crafting tools, and a bit of patience, and you’ll end up with a stack of miniature Ramen cups that hide surprise character cards. The best part? You control the rarity. No more hunting for that one elusive figure. You decide which character goes in which bag.
Why is this worth doing? For content creators, it’s a goldmine. The ASMR element of crinkling paper and the slow reveal of a handcrafted item is pure engagement bait. For hobbyists, it’s a relaxing afternoon project that yields a tangible, shareable result. And for anyone who loves Kpop or Demon Hunter aesthetics, it’s a chance to bring that world into your own hands. Let’s get into the nitty-gritty of how to pull this off.
What You'll Need
First, the materials. You’ll need a quality cardstock—I recommend 65 lb or 80 lb weight. It’s stiff enough to hold the bag shape but still folds cleanly. You can find this at any craft store like Michaels or online. For the Ramen cup design, you’ll want a glossy finish if possible, but matte works fine. Grab a pack of assorted colors: red, black, and gold for that Demon Hunter vibe.
Next, the tools. A sharp X-Acto knife is non-negotiable for clean cuts. Pair it with a self-healing cutting mat to protect your table. A bone folder is my secret weapon—it creates crisp, professional folds without cracking the paper. You’ll also need a ruler, scissors, a glue stick (I prefer Elmer’s Craft Bond for its tackiness), and double-sided tape for the flaps. If you’re printing your own designs, a color laser printer gives the best results, but an inkjet works if you let the ink dry fully.
For the character cards, you’ll need small images of Rumi, Mira, and Zoey—either printed from digital art or drawn by hand. The bags themselves require a template. You can draft one yourself: a rectangle roughly 4 inches by 6 inches, with fold lines at 1 inch from each edge. Or, find a free Ramen cup template online. Budget-wise, this entire project costs under $10 if you already have basic tools. If you’re starting from scratch, expect to spend about $30 on a starter kit of cardstock, a knife, and a mat.
Step-by-Step
Step 1: Prepare your template. If you’re drawing your own, measure a 4x6 inch rectangle on cardstock. Mark fold lines at 1 inch from the top and bottom edges, and 0.5 inches from the left and right edges. This creates a shallow box shape. For the lid, use a separate 3x3 inch square with tabs. Print or draw your Ramen branding on the front—something like “SPICY DEMON RAMEN” in bold letters.
Step 2: Cut out the template with your X-Acto knife. Here’s the trick most pros won’t tell you: always cut on the waste side of the line, not through it. This prevents the line from showing on the final piece. Score the fold lines with the back of your knife or a scoring tool. A bone folder is ideal, but a dull butter knife works in a pinch.
Step 3: Fold the sides up to form the cup. Apply glue stick to the side tab and press firmly for 30 seconds. Then fold the bottom flaps inward and secure with double-sided tape. The tape is stronger than glue for this. Make sure all edges are flush—any gaps will ruin the illusion.
Step 4: Create the character cards. Cut small rectangles, about 2x3 inches, from white cardstock. Glue or print the character art on one side. On the back, add a fun fact or a power level for the Demon Hunter. This adds replay value. Slide one card into each bag before sealing.
Step 5: Seal the top flap. Fold it down and use a small piece of double-sided tape to keep it closed. For an authentic blind bag feel, you can also add a perforated tear line—just score a line 0.5 inches from the top edge. The ASMR crinkle comes from the paper itself, so don’t over-handle the bags.
Safety First
Before you start, here’s what you need to know. X-Acto knives are sharp—like, hospital-visit sharp. Always cut away from your body, and keep your fingers behind the blade. Use a ruler as a guide, not your hand. If you’re working with kids, use scissors instead. The glue stick is non-toxic, but double-sided tape can be a choking hazard for small children, so keep bags out of reach if they’re intended as toys.
Ventilation isn’t a big deal here, but if you’re spray-mounting prints, do it outside. Paper cuts are the most common injury—keep a first aid kit nearby. And when you’re filming the ASMR unboxing, be mindful of repetitive motion. I’ve seen creators develop wrist strain from too many crinkle sounds. Take breaks.
What NOT to do: Don’t use hot glue for the flaps—it’ll warp the paper. Don’t rush the drying time on the glue; wait a full minute before handling. And for heaven’s sake, don’t try to cut multiple layers at once. That’s how you get jagged edges and a trip to the ER.
Troubleshooting
What can go wrong? Plenty. The most common issue is the bag not holding its shape. If the sides collapse, you likely used paper that’s too thin. Switch to 80 lb cardstock. Another problem: the lid doesn’t fit. Measure twice, cut once. The lid should be exactly 3x3 inches—any bigger and it’s loose, any smaller and it won’t close.
If your prints smudge, you’re probably using an inkjet printer without letting the ink dry. Let it sit for 10 minutes, or use a heat gun on low. For crooked cuts, you’re pressing too hard or using a dull blade. Replace the X-Acto blade after every 10 cuts—they’re cheap and make a world of difference.
Plan B: If you don’t have a printer, draw the characters by hand. Simple stick figures with exaggerated features work surprisingly well. Or, cut out images from old magazines. The aesthetic doesn’t have to be perfect—it’s the handmade charm that sells it. If the ASMR sound is too quiet, try recording with a contact microphone placed on the table. It picks up the paper crinkle beautifully.
The Result
When you’re done, you’ll have a set of 6 to 12 Ramen blind bags, each containing a surprise character card. The finished project looks like a miniature ramen shop display—colorful, tactile, and utterly satisfying to open. The ASMR experience is genuine: the rustle of the paper, the tear of the tape, the reveal of the card. It’s a sensory delight that translates perfectly to video.
How long did it take? About two hours for the first batch, including drying time. The second batch took half that. Cost? Under $5 for the materials, assuming you already have basic tools. What would I do differently? I’d pre-print the character art on sticker paper for a cleaner finish. Also, I’d add a small piece of tissue paper inside each bag for extra crinkle sound. Honestly, this project is a winner. It’s cheap, creative, and endlessly customizable. Go make your own Demon Hunter squad—you won’t regret it.
