I think it took between an hour and a half to two hours and a half to finish that one. It was fun though, I love doing that kind of stuff. I'm about to do the same to my mothra.
That's cool. I agree, customization and such is so fun.

Are you re-listing it(the crystal one)? I was a little surprised no one bid on it and it ended.
i gotta ask how do you custumize a tama?
It can be simple of a customizing like putting stickers on it, to getting into more complex stuff like literally changing the buttons inside it to another colour, to painting your virtual pet, to even one person I seen online took out the little background thing and make theirs glow in the dark (but of course only do that if you know what you're doing lol).
I got one custom V1 Koluki aka Eveh from here sent me earlier this year that's painted on the back and tiger stickers on the front, and a beaded thing she made to replace the original chain with ring the V1 came with.
