UPDATE!
since some people asked about it, now I have colored options for the one that want them in color.
Since color its printed on demand will take 2 days to process them (since I always have 1 or 2 pairs printed in black, but cant have all colors). I can print them in almost any basic color, like red, yellow, green, blue, pink, white, etc.
I attached an example. Prince its the same (recently I went up to 35, since material cost when up (pretty sure that was a new law in taxes from china). For people that already bought them but wants color, I have a super special discount (just charging cost and shipping).
Thanks to all, from my heart, I'm really happy every time that people like the caps
it means a lot.
