Default Markiaro Pen Cases Destroy Pen Hardware

Hello Penturners!

I have discovered a problem with my pens and the cases in which they have been stored. I am wondering if perhaps anyone else has experienced this problem and/or can offer any information/advice? My problem is this: As of late, I have noticed that the finishes on most of my pens are being eaten away in my Markiaro cases. It seems worst with less expensive pen component kits although it is also happening to the higher grade kits.

I have been storing most of my pens (all purchased from other turners) stored in Markiaro Italian Leather Cases. I have 2 40-count cases, 1 10-count case and 2 single pen cases. These cases have been sitting on top of my desk for easy access.

In hopes that the metal just needed some polishing, I have tried using gentle metal polish but to little or no avail. It looks as though the finish is being eaten away. Tiny spots are found on the metal but not the wood or acrylic blanks, thankfully!

I am at a loss. The only hypothesis that I have is that there is something in the Markiaro processing that reacts with the metal.

I spent large sums of my meager pen allowance with the expectation that my purchases would be protected. This is quite a disappointment.

Oh yes, I live in Western Washington so we do not have the heat & humidity found in much of the country. Also, since they have been sitting on my desk, they are obviously in a temperature-controlled area with relatively low humidity (40-50%) and a consistent temperature of 70 degrees F.

If anyone has any insight and can offer possible solutions, I would be most grateful. Thank you! Maria

sound like chemical they used to process the leather, remove pen, put case in garbage if it were me.

If you’re using CA as a finish and put it in the closed case the off gassing may be causing the problem. Long shot guess.

Thank you for your speculation. That was also my thought.

Thank you. I purchased all these pens. I am guessing that all of them have CA finish. The blanks are fine but the problems are with the hardware. I know that there are different qualities of pen kits but even the higher quality hardware has been affected. Will consider contacting Markiaro.

I donít know if this is the issue but we found that formaldehyde is used in some leather processing.
Wifey had a topical rash several years ago...primarily face/ neck she had been doing some pyrography and also wearing an inexpensive Harbor Freight leather apron. We discovered that formaldehyde is given off from burning wood also. Through extensive testing we found that she was allergic to Formaldehyde, gold and now she has platinum rings!
Some online checking found formaldehyde is used in a number of products...such as make up...and shoes(leather).

More things to keep you up worrying at night.
I hope you find your answer.

Charlie, be careful as she doesn't seen to be allergic to diamonds, either.

If the plating is corroded it is permanent. If its discoloration, a stronger cleaner may help. I had to look up the brand and it is not inexpensive. One would expect better.
Iíd take the pens out, clean and store them else wear. Then put one in the case that has no issues. Wait and see what happens.
What ever is causing it is strong. Just think of how long chrome plating last on cars.

I own some high end guitars with a high gloss finish. Most of the manufacturers warn of ruining their finish when making contact with leather guitar straps. This may not have anything to do with your experience - just trying to help.

Don't leave pens inserted in the elastic sleeves for an extended period.
The acid used in the manufacturing process of the elastic will damage blank and plating finish.

Innovation is the process that renews something that already exists and not, as is commonly assumed, the introduction of something new.
