• Fine-meshed, precision-ground cutter head made from high-quality carbon steel
• Very narrow cutting width – only 24 mm – for contours and fine work
• Safe cut, very close to the skin, approx. 0.5 mm #30
• Made in Germany

 Long Lasting. 

these blades need to be screwed on(they do not snap on/off) 

*use a can of air(like for a computer) to blow out between cutter blades(you will be shocked at how much hair is in there!) and use scissor oil with the long thin tip to get oil between contact points. i get blades to last me year this way.
