Available in seven distinct styles for different applications, Bonkote™ Bon Pens are easily cleaned and maintained with alcohol or water, depending on flux use. The pens are ESD Safe and RoHS compliant and accept a whole array of fluxes. Both the tips and cartridges are available for purchase, so you can reuse either for extended lengths, without having to buy new assemblies. You can also use a single cartridge, and simply buy the various replacement tips to save on costs. The special polymer used in the cartridge allows for repeated use, without performance degradation.
