I bought these files because they were thinnner than some other brands allowing me to save space for more paper that will go inside (not that it's too thin or not durable enough because it's too thin. Also I ended up getting a better deal at the store than online ([$] each box for 2 or more boxes).
Four of the five colors are fine and work well when sequenced properly in spectrum fashion--green blue purple red. Dump the yellow though--ghastly. Are packaged so one folder is left tab next is center last is right. I found that useful.
