"With the volume of goods that cross our borders on a daily basis there are times those things come in that go undetected," said Wills.
For example, agents are finding more counterfeit circuit breakers.
They say it's often hard to tell real from fake, but typically, the switches on fake breakers don’t flip as smoothly, breakers are usually lighter, and the equipment may not have proper labeling such as the amount of wattage and ampage marked on the breaker.
In 2010, agents seized nearly 100,000 counterfeit breakers from a supply company.
In October, they arrested two men for trafficking dozens of fake air bags made by a company in China.
Agents say they are all reminders, especially this holiday season, what you buy may not only be illegal, but putting you at risk.
A warning for moms: agents also still seeing a lot of counterfeit baby food and powdered milk.
So, what happens to those thousands and thousands of seized counterfeit items? Agents said all of it will get destroyed.
