Wonderflex or Worbla

Choosing a thermplastic can be rather difficult in cosplay. You have two options that seem in a lot of ways similar. So when you find yourself stuck choosing between Wonderflex or Worbla here’s some similarities and differences between them to help you ultimately choose which is right for your cosplay.

Wonderflex

Types of Wonderflex

• Wonderflex: the classic scrim-reinforced thermoplastic with its own adhesive.
• Wonderflex Pro: no scrim reinforcement, more flexible and able to capture finer detail.
• Fosshape: a felt-like, heat-activated fabric (sometimes called “Foss Shape”) sold by the yard.

Wonderflex Pros & Cons

Pros

• Strength / Durability: Very strong and sturdy; the scrim reinforcement helps prevent tearing.
• Flexibility: Moderately flexible — the scrim gives shape but limits how much you can stretch.
• Adhesive: Has its own built-in adhesive; bonds well to itself.
• Texture: Slightly textured due to the mesh, which some people like for priming or painting.
• Workability: Can be activated with a steamer, hot air gun, or hot water.
• Weight: Lightweight, suitable for wearable armor or props.

Cons

• Scrap Use: Scraps are less reusable in the way Worbla scraps are (they don’t blend quite the same).
• Detail: Less suited for super fine detail work compared to a scrim-free thermoplastic.
• Finish: The mesh texture may require more priming to get a smooth finish.
• Cost: While cheaper than some Worbla types, large sheets or yardage (for Fosshape) can add up.

Ratings (out of 5):

• Texture: 3.5
• Flexibility: 4
• Adhesive: 4
• Strength: 4.5

Worbla

Types of Worbla

• Worbla’s Finest Art: the classic, original Worbla sheet.
• Worbla’s Black Art: smoother surface, good for detailed work.
• Worbla’s TranspArt: transparent thermoplastic, ideal for visors, gems, etc.
• Worbla’s Mesh Art: has a plastic mesh backing, similar in reinforcement to Wonderflex
• Kobracast: an open weave mesh thermoplastic.
• Pearly Art: a pearly-white version of Black Art.

Worbla Pros & Cons

Pros

• Variety: Wide range of versions (Finest Art, Black Art, TranspArt, Mesh Art, etc.) to suit different needs.
• Reusability: Scrap pieces can be reheated and remelted into usable material.
• Detail: Black Art and Pearly Art allow for fine detail and smooth finishes.
• Adhesive: Many types (e.g., Finest Art) are self-adhesive when heated, so they bond without extra glue.
• Strength: When layered (or sandwiched with foam), Worbla can create very rigid, strong structures.
• Finish Options: TranspArt gives you transparent elements for visors or light-diffusing props.

Cons

• Activation Temperature: Some types (like TranspArt) need higher heat (120°C) to become usable.
• Work Time: Cooling can happen quickly, so you need to work intentionally.
• Texture: Some sheets (like Finest Art) can be grainy; require more sanding / priming.
• Cost & Availability: Depending on the version, cost can be high; some variants may be harder to find.
• Heat Sensitivity: If overheated (with a heat gun too close), there’s risk of burning or stickiness.

Ratings (out of 5):

• Texture: 3 (Finest Art) to 4.5 (Black Art)
• Flexibility: 4 (some types are more flexible than others)
• Adhesive: 4
• Strength: 4

Where to Shop for Worbla & Wonderflex

• Wonderflex: You can buy directly from Wonderflex World, which offers Wonderflex, Wonderflex Pro, and Fosshape.
• Worbla:
  • The official Worbla website lists retail storefronts.
  • Blick Art Materials carries Worbla products.
  • Amazon also carries a small selection of Worblas

Conclusion

Choosing between Wonderflex and Worbla comes down to your project needs:

• Use Wonderflex if you want a reliable, strong, slightly textured thermoplastic that’s great for building wearable props, masks, or lightweight armor. It’s sturdy, has built-in adhesive, and is somewhat more forgiving.
• Choose Worbla if you need variety — whether that’s fine detail (Black Art), transparency (TranspArt), or mesh backing (Mesh Art). Its scraps are highly reusable, and you can create very rigid, sculpted pieces by layering or mixing with foam.

If you’re just starting out, consider picking up a starter pack to experiment without committing to large rolls. For more advanced builds, a combination of Worbla types might be your best bet.
