* Bristles/Fibers:
* Sigmax Fibers: Sigma's signature synthetic fibers. They are engineered to mimic the performance of natural hair brushes but with added benefits like being cruelty-free, hypoallergenic, and easier to clean. Sigmax fibers are designed to pick up, distribute, and blend makeup products effectively. They're a popular choice for liquid and cream products.
* Natural Hair: Some Sigma brushes use natural animal hair, although they have been phasing them out. Historically, they used hair like goat or sable in some brushes.
* Handles:
* Wood: Most Sigma brush handles are made of wood, often sourced sustainably.
* Various finishes: The wood is usually coated with a protective finish, which can be paint, lacquer, or other materials to provide durability and a comfortable grip.
* Ferrules:
* SigmaAlloy: Sigma's ferrules are made from SigmaAlloy, a metal alloy. It is designed to be durable, scratch-resistant, and plated for added strength and aesthetics. The ferrule is the metal part that connects the brush head to the handle.
