Hello!
 
Hi,
 
Yeah right! I can see trying to enter the Philippines (or any other of
the major shell market areas) with trans-portable X-Ray equipment.
 
"Well you see Sir (customs person), ah, I plan on buying some very rare
(read; expensive), ah, sea shells and I have to detect fakery by using
this here apparatus."  "HA! HA! HA! Step right this way Sir (customs guy
ref to you). We are, ah, going to X-Ray your cranium for content." How
do you like them Guavas!!
