I was disappointed though when I opened the triox box. I remember this stuff as being about 2.5-3 inches long and scored so you could break it into three pieces. This was about the size of a silver dollar? I know that the military no longer issues Trioxane but when did the smaller bars happen?
I bought some as recently as about a year and a half ago (NSN:9110-00-263-9865 & MIL SPEC: MIL-F-10805D) and they are approximately 3" long (by 1" wide).
