I have some special tools i've been given. i would like to put these tools in an aluminum briefcase so i can take them with me when i need them. can someone tell me what materials i shoull use in the briefcase? i want something i can line with velvet preferably. should i go with styrofoam or something else? does anyone know of a spray/expanding foam i can use? i want to be able to scoop out the material so that the tools will nest into it.
