I like the design, it solves the problem most dividers have. I does add weight, which might be a problem with measurements, but the added stiffness might out weigh that.
Would love to try using them, If I could trouble you to try them out for measuring if you could and perhaps telling us what you think?

They do work great... I have a few.... but what is odd with such a strong design you would think they would make them bigger than the 5".... I think they only made these in 3" and 5" size.... also did insides.
