QuoteThis thread should be renamed "REVEAL A GOOD CONCEALMENT METHOD TO LAW ENFORCEMENT".You are right, this is a bad idea.By this logic, assuming I'm interpreting you correctly: Every method mentioned in this thread will automatically be searched by LE/Customs automatically with no regard if the product could actually be legit. Now granted this "could" happen and if it does we'll see plenty of articles the coming months of people who are getting their legal Blu-rays/DVD-cases opened and their food orders seized for long amounts of time, because no matter how many drugs are getting sent I can assure you more than 90 % of them will be legit. Time will tell. :)Quotedear LEOI have placed drugs inside the barrel of each of your service weapons and the only way to access them is to look directly into the barrel for them and pull the 'secret' lever disguised as the guns trigger. Make sure the gun is loaded or else the evidence will self destruct.While most likely meant as a joke there's nothing preventing doing something similar to this, although it would probably be more illegal than the drugs themselves. Include a metallic container with a small subsection with a corrosive acid which gets released until the container is opened in a very specific manner unbeknownst to anyone but the recipient. Now chances are the customers will do it wrongly even with very specific instructions and get a big hole in their desks or something so it's probably not worth exploring that idea that much. ;D----------Now I forgot to mention a few methods which I had already written up, so here it goes:* Hollowing out ObjectsAny book or magazine which is thick enough could be hollowed out, to see an example on how someone does it: https://www.youtube.com/watch?v=O_5wQjFrZe8Another type of object could be various types of batteries, the best type would probably be AA or AAA: https://en.wikipedia.org/wiki/File:6_most_common_battery_types-1.jpg A small MBB would fit in each one. This would probably require some metalworking equipment and knowledge as it's probably not safe to mess around with batteries without knowing what one is doing. * LaminatingLamination is a process which can be used to for example put a plastic layer on top of a painting. If one includes a MBB inside the painting and put a laminate layer over it it would not be noticeable by touch if there's anything inside the painting. Lamination is mostly used for ID cards and such otherwise.* Mixing Product into ObjectsAlthough this is not a dog proof solution if they open all layers it would be X-ray proof. It's been done before and failed due to the fact no MBB were involved: http://www.reuters.com/article/2008/05/30/us-mexico-drugs-idUSN3031343320080530* Protein PowderAccording to http://www.give2thetroops.org/items.htm Protein Powder is one of the most commonly sent items to American troops in so called "care packages". The added benefit of this many Protein Powder packages already contain powder to begin with and their structure is very similar to a MBB. For some images on how these packages/bottles look in general, see these two Swedish training vendor links: http://www.gymgrossisten.com/1/sv/artiklar/kosttillskott/proteinpulver/index.html / http://www.vitaminvaruhuset.se/aminosyror-protein
