What separates Helios from other needle cartridge brands is the combination of their ultra-smooth feel, just the right tension, and a fair price.
Helios recently released a new model of cartridges called 'Helios Red Label'. These red-tinted cartridges feature a membrane system which replaces the original rubber band model. Membrane cartridges are considered to be a safer system that stops any back flow of ink entering the grip. We are slowly replacing all original Helios with Red Label Helios. The sizes and configurations available in Red Label are indicated in the drop down menu.
Use them with any cartridge grip. Each box contains 20 cartridges.
