Lagann with Revoltech Gurren lagann: “Your drill is a drill that will pierce the heavens!”
Simon can still be place inside the cockpit even when coving the top cover
This lagann has really strong and good articulation joints. this figure is definately well worth the money.
lagann looks cool but simon on the other hand isn’t. expression looks stale.
btw bro u going for wonderfest next Aug?
danny has invited me to attend and i’ll love to have someone to show me around since this is my first trip to japan. ^^;
typo, i meant this aug.
Wonderfest? Not sure yet ^^;
So you planning to visit Tokyo in August?
you seem to be in good contact with Danny. He never reply my question or mail :X
But if I could tag along with you to the show, that would be cool
yeh.. Simon… could be better if they include face change feature like Figma.
if i can find a guide then i will seriously consider coming. ^^;
i admit its a bit rush on my end. can’t find any local buddies to tag along.
haha, danny is a busy man, he mentioned he receive hundreds of mails each day. he also can’t can’t answer all the comments on his blog. but since bro u live in tokyo maybe can arrange for meet him up. will be awesome. ^^;
Ic, I should be working on weekdays, so kinda hard to show you around. Can only do it on weekend.
I did try to ask Danny on meeting him, say if he going to drop by akiba, give me a shout. But no reply from him LOL~
Its Ok anyway, maybe will have chance to bump into him
Where can I find this set? I want to get it! I would love to visit Japan but the airline tickets are so pricey. Sigh
