Bummer..

I've had a couple of Naish boards including a 10' Mana GT and I've not seen that before.. What did the shop say?.. What did Naish Australia say?
These boards are shipped in and out to the shops all sealed up in a big box so there is no way for Naish to check or even know about it till someone tells them.
The shop should have checked and noticed it when they unpacked it and before it got to you if it was there originally or if its happened since you recieved it it's up to you to let them know..
