Thought I would share this find with all of you. Wal Mart has the small hand held blacklight in their Halloween department for $6.97! This is the one with the small fluorescent tube on one side and a regular flashlight on the end. About 5" long total.
This is not the LED flashlight blacklight, but it works very well. Runs on a couple of AA batteries. I used these to carry to fabric/craft stores before I purchased the LED one, and still have one I carry at times.
I have a couple of those! Good thing I got a few actually, because since seeing them in my local craft store once, I've not seen them again, not even during Halloween. They're very useful, although not really all that bright. I had to hold it close to the materials in order to get any effect at all.
