Ten kilograms of the synthetic drug methamphetamine, also known as crystal meth, lie securely sealed in a plastic bag in front of a large, round wooden mosaic.
The hollowed-out wooden object served as a smuggling hideout and was sent from Mexico by courier service.
"One of the focal points in the fight against drug-related crime is on synthetic drugs, because the quantities of these drugs exploded again during the Corona crisis," says Oliver Bohlender, head of the customs investigation department.
At its annual press conference at the airport on Thursday, the main customs office showed confiscated evidence from 2021 - including drugs and doping substances, prohibited weapons, counterfeit products and preparations from protected animals.
In addition to stun guns and brass knuckles, testosterone pills and counterfeit cordless circular saws are on display.
A whale bone weighing around 15 kilograms from Namibia was also smuggled in the luggage and confiscated by customs.
The fight against cross-border smuggling and illegal trade in narcotics still accounts for the largest part of the investigative work of the customs investigation office.
Much of the chewing drug khat, which is grown in Africa, is still being seized, and cocaine is increasingly being hidden in lipsticks.
"There are no limits to your imagination," says the head of the main customs office, Markus Tönsgerlemann.
A total of 26,040 kilograms of drugs worth around 129 million euros were seized in postal, freight and tourist traffic.
"Fighting drug smuggling remains one of our most important goals," says Cosima Schmidt, head of the customs investigation office.
Sniffer dogs will also find cash
The investigators of the main customs office are supported by sniffer dogs.
There are currently 26 teams with narcotics, endangered species, tobacco and cash detection dogs on duty.
On Thursday, officers with the drug detection dog Yngvi demonstrated how such a control works.
The Weimaraner male quickly searches the ten suitcases lined up.
He remains by the conspicuous piece of luggage until his guide confirms the find with a clicking noise.
But sniffer dogs are not only used for drug checks, they are also helpful when looking for cash.
From banknotes in hollowed-out books to banknotes wrapped in plastic and hidden in filled shower gel bottles to rolls of money in chocolate bunnies - the hiding places are diverse.
"As part of Germany's security architecture, we are committed to fighting moderate, serious and organized crime," says Schmidt.
It's not just about getting illegal goods out of circulation, but also about tax justice and the protection of citizens.
