So again I also wonder is that mean toy blasters put in on check in luggage should be ok, juz not hand carry I think.

ahh..that said it. i guess for the sake of avoiding problems with my flight, i decided not to bring any nerf then, even in luggage..besides, its not that important tho..that'll have to wait
should be fine in cargo. nerf is pretty known to be toys by customs. unless, you buy those 3rd party cosmetic kits. that's a different story. as is, should be fine to even post.
i guess i have to wait until i finished study and bring back all in container with my other personal items. probably safer and less hassle that way. wont be modding those nerfs until becoming real-thing lookalike.. haha.. that wud spell trouble with local customs also..
