Blades: High-carbon steel with a new titanium and DLC coating on recent models.
Housing: Durable polymer plastic.

To use the Wahl Cordless Barber Magic & Detailer Combo Kit, you should use the Magic Clip for bulk hair removal and blending, and the Detailer Li for outlining and detailed trimming.
Before you begin
Charge the tools: For optimal performance, fully charge both the Magic Clip and the Detailer Li before first use. A single power cord can be used for both.
Oil the blades: Apply a few drops of Wahl Clipper Oil to the blades of both tools before each use to keep them sharp and rust-free.
Prepare the hair: Ensure the hair is clean and dry. Using the clippers on wet hair can cause them to become clogged.

Combo kit advantages
This kit offers the primary benefit of having a complete cordless system for both bulk hair removal and precision finishing.
Professional convenience: Both tools run on lithium-ion batteries and offer cordless operation for maximum freedom of movement in a professional setting.
Complete kit: The set provides all the necessary tools for a full range of haircutting techniques, from full fades to precise detailing.
Upgraded blades: Newer versions of the combo feature titanium and DLC-coated blades that stay cooler, resist corrosion, and remain sharp up to four times longer than standard blades, according to manufacturer testing.
Reduced clutter: The ability to use a single power cord to charge both units helps reduce clutter at the barber station.
