What Are Perler Beads?
Updated May 2026 · ~5 min read
Perler beads — also called fuse beads, melty beads, iron-on beads, or by their main competitors Hama and Artkal — are small plastic cylinders you arrange on a pegboard to make pixel art. Heat them with an iron and the beads bond into a single rigid piece. They have been the default kids-and-grown-ups craft for over 25 years, and the technique is straightforward enough that a six-year-old can finish their first project in 20 minutes.
~ ONE-PARAGRAPH ANSWER ~
Perler beads are small (5 mm) plastic cylinders made from non-toxic polyethylene. You stand them on a pegboard in any pattern, cover with parchment paper, and iron — the heat fuses them into a permanent piece. They come in 100+ colors and are sold in starter kits for ~$15. Every craft term you have heard — "fuse beads", "melty beads", "Hama", "Artkal" — refers to the same thing.
What Are They Made Of?
Perler beads are made from low-density polyethylene (LDPE) — the same food-safe plastic used in milk jug caps and grocery bags. The plastic is colored throughout (not surface-coated), so the dye does not fade, rub off, or come out in water. Perler-brand beads carry ASTM F963 toy safety certification and are free of BPA, lead, and phthalates.
Each bead is a tiny hollow cylinder roughly 5 mm in diameter and 5 mm tall (Midi size — the default), with an opening through the center. The opening is what makes the beads stack on a pegboard's plastic pegs.
How Do They Work?
- Arrange the beads on a pegboard — each peg holds one bead upright.
- Cover with parchment paper (NOT wax paper — wax melts).
- Iron on medium heat for 10–20 seconds. The bead walls soften and bond to their neighbors.
- Cool, peel, flip, iron the back side — fusing both sides makes the piece more durable.
- The result is a single rigid piece that still shows the round bead shapes and tiny holes.

What Sizes Do They Come In?
| Size | Bead Diameter | Best For |
|---|---|---|
| Mini | 2.6 mm | Tiny earrings, charms, jewelry pendants. High detail in small space. |
| Midi | 5 mm | The default size — 95 % of patterns assume Midi. Pixel art, keychains, coasters, decorations. |
| Maxi (also "Biggie" by other brands) | 10 mm | Toddlers (ages 4+) practicing fine motor skills. Larger statement pieces. |
| Bucket / Standard | 5 mm | "Bucket" usually refers to volume, not size. A 22,000-bead bucket of Perler is just Midi beads sold in bulk for big projects. |
Midi (5 mm) is the default — when a pattern just says "Perler beads", it means Midi. Hama Midi and Artkal S-5mm use the same pitch and are interchangeable.
Perler, Hama, Artkal — All The Same Thing?
Almost. They are different brands of the same product. The technique works identically across all of them. Differences are in palette, price, and where they are easiest to buy:
| Brand | Main Region | Notes |
|---|---|---|
| Perler | North America | The original brand-name in the US. Largest single-color packs. |
| Hama | Europe | Swedish brand, the European default. Slightly more vivid colors. |
| Artkal | Global online | Best price-per-bead. Wide color range including pastels and metallics. |
| Pyssla (IKEA) | Global | IKEA-store house brand. Identical pegboard pitch to Hama. |
| Nabbi | Northern Europe | Cheaper Hama alternative sold in craft chain stores. |

Are Perler Beads Toxic?
Genuine Perler beads are non-toxic. They carry the ASTM F963 toy safety certification (the standard governing children's toys in the US), are free of BPA, lead, phthalates, and latex, and the polyethylene plastic itself is food-safe.
The plastic smell during ironing is normal — it is the volatile binders releasing as the plastic softens. Vent the room (open a window or run the kitchen hood). The smell is not actively dangerous in the small quantities typical for craft work, but it lingers and can trigger headaches in poorly ventilated spaces.
Choking hazard for children under 3 — the beads are small enough to swallow. Recommended ages: 4+ for Maxi beads, 6+ for Midi, 8+ for Mini.
Off-brand fuse beads sold at deep discount sometimes lack the same certifications. If a bead has no brand label, consider its safety unknown — fine for ironing in a vented room, but not the right choice for a young child or for projects that touch food.

Frequently Asked Questions
What are Perler beads made of?
Low-density polyethylene (LDPE) — the same plastic used in plastic shopping bags and food containers. The dye is mixed into the plastic itself, not coated on, so colors do not fade or rub off. Perler-brand beads are tested non-toxic and free of BPA, lead, and phthalates.
How do Perler beads work?
You arrange the cylindrical beads upright on a pegboard, then apply heat (most often via an iron and parchment paper). The plastic softens and the bead walls bond to neighboring beads, creating a single rigid piece. The heat is high enough to fuse but not high enough to fully liquefy — which is why finished pieces still show their characteristic ring shape and small holes.
What size are Perler beads?
The default size is Midi at 5 mm in diameter and 5 mm tall. There are also Mini (2.6 mm, for jewelry detail), Maxi / Biggie (10 mm, for toddlers), and various branded sub-sizes. When a pattern says "Perler beads" without specifying, it means Midi.
Are Perler beads toxic?
Genuine Perler-brand beads are non-toxic. They are made from food-safe LDPE plastic, contain no BPA, lead, or phthalates, and have certifications including ASTM F963 (US toy safety standard). The smell during ironing is normal — vent the room when fusing — but is not actively harmful. Off-brand fuse beads with no certification can be different; if a bead is sold at deep discount with no labeling, treat it as unknown material.
Are Perler beads safe for kids?
Yes, with age guidance. Ages 4+ for Maxi (large) beads, 6+ for Midi, 8+ for Mini. The choking hazard for under-3s is the main concern. The ironing step is always adult-only — kids can place beads, but they should never handle the iron, oven, or heat gun.
Are Perler, Hama, and Artkal beads the same?
Functionally yes for the standard 5mm Midi size — same pegboard pitch, same fusing technique. The differences are minor: palette range, fuse temperature sensitivity (Hama and Artkal fuse a touch faster), and price. You can mix all three on a single project without any problem.
Where did Perler beads come from?
Fuse beads originated in Scandinavia — the Hama brand has been around since the early 1970s. Perler launched in the US in 1996 and became the dominant North American brand. Artkal is a more recent Chinese brand that opened up wholesale and online direct-to-consumer pricing in the 2010s.
How long do Perler bead designs last?
Indefinitely — finished pieces are essentially solid plastic and do not degrade under normal use. Avoid prolonged direct sunlight (UV slowly yellows white beads over years) and dishwashers (heat can warp ironed pieces). A finished coaster used daily can last decades.
Can you reuse Perler beads?
Beads that fall on the floor or were never placed are still reusable. Beads that have been ironed and fused are permanently bonded — they cannot be popped off and reused. If you make a placement mistake, fix it before ironing.
