Mast PRO Cartridges 4 Flat KF

Buy the Mast PRO 4 Flat KF cartridge individually — take exactly the number of needles you need rather than paying for a full box. Perfect for adding the wider flat to your kit, replacing a single module between appointments, or working without surplus stock on the shelf.

The 4 Flat KF is a filling and shading configuration with one needle more than the 3 Flat: the flat arrangement with wider needle spacing covers slightly more surface per pass while still laying pigment down gently and evenly — well suited to lip blush and soft gradients in ombré lips and ombré brows. Every cartridge is original Mast PRO stock taken from the sealed 20-piece box and individually sterile-packed.

Why buy single needles

• Order exactly what you need — no leftover cartridges gathering dust.
• Test before you commit — compare 3 Flat and 4 Flat before buying a box.
• Mix and match — combine liner and flat modules for one session.
• Always original — sealed, individually packed Mast PRO cartridges.

Highlights

• 4 Flat KF — soft shading and smooth colour transitions
