striped aluminum spike side effects?

Recently in a trade i got some apike side effects and looking closer i noticed they ate striped in color, are these special edition or do they come with a special edition yoyo or what? I dont think i have ever seen side effects this color.

Just wondering if these are special or limited edition side effects or what yoyo they came with:)
Thanks

The orange aluminum spike side effects on my chik look very similar. Perhaps they are from a purple chik?

That’s what I was thinking.

It’s part of the laser engraving for the Chik! It’s part of the logo.

Ah so they are chik side effects, thanks! Are the orange ones striped orange or all black striped?
