Lure Mold Boxes for Sale

First off, what would you call these I am looking to sell them? They are boxes that come apart and are used to make silicone fishing lure molds. I have 3 as you can see here they are Large Medium and small. Right now I am asking $40 for the Large, $35 for the Medium and $30 for the Small one or all 3 for $100 and I will ship if you are willing to pay to ship.

Hi Jeff, what are the inner measurements on them if possible, thanks

Sorry these are already sold sorry.

I see. no worries.

Hello
What are these boxes made out of aluminum?

No, I believe they were steel heavy as hell but they are sold.
