Head Radicals

I decided to take a picture of the different versions of Head Radicals that I've currently got. Below is a timeline from another post in this subforum from earlier this year. The (X) after the version simply denotes that I have that version.

Nice lineup!

Any ideas as to why/how your left Zebra has yellowed so much more than its cousin?

seems fairly common afaik, but I'm real curious why some & not all

looks like its the white areas in the printed wrap not the clear gel coat
that's gone yellow. (The words at 6 o'clock stay white doesn't yellow.)
Polishing surface doesn't do much.

Also it yellows very even with no shadows so I'd rule out 20yrs UV from
constant exposure to sunlight or fluoro/halogen lighting.
Mine doesn't stink like previous owner was a chain smoker either.

Perhaps it's 2 different substrate the wrap is printed on...

CandyCane TT the softest Radical ever. As flexible as an ugly stick.

Thanks, Tamiya!

Not sure what caused the Zebra to yellow so much. It plays great, though. I really like the TT Rads!

I think UV rays caused it to yellow.

Nice set!

Sold my 2 zebras mp's but it appears I might have a chance of buying them back

Never was ever to get my hands on even one candy cane TT rad always on my wish list.

Again, nice collection thanks for sharing it!!

Btw one of my zebras had the yellowing going on, not so sure why. Bought them both new.
