2-Kester 951 Soldering Flux Pen Low-Solids, No-Clean 10ml

These are not real Kester flux pens. The markings are different and they don't have the same tips. They leak like crazy and you must tip them up to keep the flux from leaking out. The flux does seem to work and it is indeed no-clean flux. So I'm giving it two stars for the much better price and the fact that the flux does appear to work.

Good seller and product. Watch the experation dates on this this type of product.

I ordered these and the pens were leaking as well. The flux was mostly gone after just a few light uses. I ordered from epartsetc.

One of the pens was open inside the package leaking to an empty state. Evidently poor wrapping! Seems like a waste of money.
