The official DeWalt sealed packaging says that the bulbs are made in Japan. Amazon's packaging was sturdy. I included a couple of pictures. The filaments look nearly perfect as you can see. I do some serious soldering. The filament connection looks strange to me, but others can judge for themselves. Overall, the bulbs/packaging looks fine, buying this product is a bright idea. Plan to use it in my Bosch 10.8/12 volt flashlight.
