Are these cartridges safe and compatible with my machine?

Each cartridge is E.O. gas-sterilized and intended for single use, which supports infection-control protocols when combined with proper studio hygiene. They are specifically made to fit the Charme Princesse EM40 series permanent makeup machines; compatibility with other brands depends on the machine’s cartridge interface. Always confirm fit before use and follow local regulations for disposables and sharps disposal.

• E.O. gas-sterilized to maintain sterile packaging until opened
• Single-use design reduces cross-contamination risk
• Engineered for Charme Princesse EM40 series cartridge ports

Which needle sizes are available and when should I pick 1R?

The EN40 line comes in multiple configurations—1R, 2R, 3R, 5R, 7R and flat/fan options (3F, 5F, 7F)—so you can select the needle geometry that matches the technique. Choose 1R when you need the finest detail: hair-stroke brows, delicate liners, or precise microblading-style strokes. For shading or thicker lines, consider higher-round counts or fan/flat varieties.

• 1R: single fine line for hair-like strokes and ultra-precision
• 2R–7R: progressively wider groups for bolder lines or shading
• 3F–7F: flat/fan options for shading and color packing
• Each style sold in 10-piece sets to match appointment volume

Who this is for: Charme Princesse EN40-1R cartridges suit permanent makeup technicians, apprentices, and cosmetic tattoo artists who use the Charme Princesse EM40 series machines and want reliable, sterile single-needle cartridges for precise micro-pigmentation. They are also useful for training students practicing fine-line techniques or experienced artists seeking consistent single-needle performance. If you require cartridges for heavy shading, consider larger round counts or flat/fan options from the EN40 range.
