Soft transitions and controlled shading with the Shader Essential Pack
Kwadron Cartridge System Shader Essential Pack is not a random selection. It is a deliberately curated essence of the Kwadron Cartridge System, created for artists who seek consistency and control. Inside, you’ll find the most frequently chosen Round Shader configurations, used daily by tattoo artists around the world. 
Every Round Shader cartridge in this pack was developed with full control over shading in mind. Whether you’re building subtle tonal transitions, smooth gradients, or depth in larger areas, the needles work evenly and fluidly - exactly as expected. The characteristic stability and precisely engineered Kwadron construction allow you to shade calmly and consciously, delivering reliable, repeatable results at every stage of the session. 
The Essential Pack is the ideal starting point for discovering a workflow based on cohesive, dependable tools. Instead of experimenting, you begin with configurations trusted by professionals.
What’s inside the pack?
Each of the 6 configurations has been designed for precise work where control, soft transitions and clean saturation in smaller areas are essential. The set allows for smooth tonal build-up - from delicate shading to more defined areas while also softening edges without losing sharpness. It’s a solid foundation for conscious, consistent work with one type of cartridge throughout a single session.
 
The set includes 3 pieces of each of the following sizes: 
25/3 RS & 30/3 RS – For delicate shading, soft tonal transitions and subtle form modeling. 
30/7 RS & 35/5 RS – Versatile configurations for smooth shading, building depth, and even fills in small to medium areas. 
35/7 RS & 35/9 RS – For more intense shading, fast coverage of larger surfaces, and building richer, more saturated shadow areas.
