Ladies class, class.
Very nicely.

Another photo in a year, when I live

A lot also depends on how the bleached equipment is stored.
From my observations, storing in a foil bag better protects against the return of jaundice, while storing loose in cardboard boxes speeds it up a bit.
Apart from direct exposure to sunlight

nice, nice, you can see that this copy was heavily used
and I prefer the same color as they are and do not bleach

Unfortunately, these keys are not a very grateful whitening material. 4 months have passed and bile is slowly coming back ...

As you can see, everything beautiful ends quickly.
I have a Timex in which each key turns yellow differently
Some, however, not at all.

But what, dirty?

looks moldy.

Anyone grew mold for penicillin?

If it's mold, it's interesting to see what was growing inside the enclosure. : P
