Handwritten Capacitor Values?

Does anyone know why the rating on these Sonic Caps appears handwritten.
Has a cap of a different value been modified, or has the stamped rating simply been altered?

I'm not sure why, but I had the same thing happen on the Sonicaps I used for my JBL L80t rebuild.
I wonder if they were made for one value but tested at a different value. Or they may have been a customs value that they made a limited batch of???? -
Once the cap is made you can't alter the value, so definitely not that.
Almost looks like a printer problem as part of the u is also touched up. You can always measure the cap to check the value and feel free the call Sonic Craft to ask why. Real nice friendly folks.Political Correctness'.........defined

These excellent caps always come with the value handwritten and cost significantly more than Sonicap.

According to their product description: "Tolerance is better than 5%". After a production run, all the capacitors are measured. If their measured value falls outside the + or - 5% tolerance, they're put aside, and sold as custom values. 33uf is a common value available from many different manufacturers. 34uf isn't, but I'm pretty sure Jeff knows Polk's vintage Monitors use that value a lot, so he probably bins high value capacitors from a 33uf production run that are within 5% of 34uf, and hand labels them.
Every 34uf Capacitor I've ordered from Sonic Craft was handwritten.Home Theater/2 Channel:
