Galvanized Steel: The industry standard. Steel wire is coated with zinc to prevent rust, making it durable and cost-effective.

Nickel-Plated Steel: Offers a bright, silver-toned shiny finish. It provides good corrosion resistance and is often preferred for a "premium" look.

Plastic/Vinyl-Coated: Steel wire encased in a colored plastic layer. These are rust-proof, provide extra grip (non-slip), and are popular for color-coding systems.

Stainless Steel: Used for high-end or medical/industrial applications where absolute corrosion resistance is required. More expensive than standard steel.

Wire Gauge (Thickness): A thicker wire (measured in mm) results in a stronger, more rigid clip with higher clamping force.

Design/Shape:

• Gem (Classic): The standard "oval within an oval" loop.

• Non-Skid/Corrugated: Features small indentations (waves) in the wire to provide extra friction against paper, preventing the clip from sliding off.

• Triangular/Other: Specialty shapes designed for specific structural stability.

Packaging Unit: Standardized counts per box (e.g., 100 clips/box) are critical for warehouse and retail inventory management.
