Like those boxes from the United States Postal Service,"If It Fits,It SHIPS"!
"IF" it will "FIT" in a large suitcase,bring it!
That said,I always come through customs in Santo Domingo,I haven't been checked in about 9 years!
I have afriend who lands in Santiago,who says they X-ray all luggage there.
If they find it there,you may have to pay something.
The fact that is "Used",and "Not For Sale" doesn't hold any water here,EVERYONE says that,no matter what!
Bottom Line,I would bring it.It's not needed in the USA,but here,it will be!
Good "Smuggling"!
