At the last place I worked management proclaimed that they were going to use all carbide end mills, guess who was there to relieve them of there HSS end mills. A lot came without a container, the solution to this issue was PVC pipe and the end caps for said pipe. Put a cap on one end give it a little whack with a hammer the other end just push on. Then write on the pipe what type of end mill lies within, size, 2 flute, 4flute double end etc. Magic marker works well for marking.
