Firearm case foam review. This is a great product. The material is excellent and appears to be of the same quality that I have in all of my forearm cases. I will be using this to replace or add where it is necessary. I absolutely think this will help hold firearms nicely and securely in place to help preserve them for safe storage, specifically after cleaning. Thank you for this product 5 stars

I was sitting here the other day, staring at my bag of old sockets, wondering if there was a good way to organize them - enter this "pick and pluck" foam - it's exactly like it sounds - you pluck out squares of foam to make compartments for whatever you're organizing. I have a few briefcases lined with the same stuff - great for storing electronics, camera equipment, musical gear, art supplies, coins...plus probably hundreds of other things. Will definitely work great to get my sockets in some sort of order, so I'm not rifling through the bag every time I need a certain socket. Might be a little pricey for four sheets of foam, but it just might pay you back in saved time, or possibly lost or damaged equipment.
