Help! Nemosine Barrel Screwed On Too Tight

[lourdesgirl101]

I need help. The barrel of my Nemosine Singularity is screwed on so tight I can't get it to budge. I've tried putting it under cold water, cold water and soap, paper towels, Clorox wipes, and even a little rubber shaped hand that we use to open jars. Nothing is helping this time so it is sitting in my drawer. I would like to change the cartridge eventually. At least cartridge is still full despite not in use for 1-3 months!

You have probably tried this already, but I would soak it for several hours in cold water.

Try this:

 

First, put the pen in your fridge until it is thoroughly chilled.

 

Then hold the barrel in hot running water, and use your jar grip -- two if you can, to unscrew it.

 

Chilling the pen should cause slight contraction. Heating the barrel should cause it to expand. Once it's bigger, the barrel should unscrew more easily.

 

The reason I only recommend fridge-cold and tap-water hot is because I don't know exactly what material is used in the pen, or how well it deals with thermal shock.
