Perfect project for forming to odd shaped items and provided the protection required! These were awesome!

The product is a perfect packing tool for more fragile items. Practice makes perfect with these We have used Expanding Foam many times before, so no issues for us. We use Expanding Foam for our most delicate items.

Be sure to select the correct size for the box to risk busting and or reduced all around protection. These work great to ship some camera lenses and a couple of Fenton Bells. The packages were ready to ship in less than a minute just pop and place. No need to fit in bubble wrap or cardboard. Excellent!

So you learn real quick to tap A and B pouches over and over til the liquid bursts and then QUICKLY spread it all over the pouch because as it spreads it gets super hot before it solidifies. If you don’t push it around quickly it won’t disperse to all four corners of the pouch evenly.

These imo are a wast for the they cost. They only fill about 50% of the given bag space. So plan accordingly when you select the size. There isn not enough of the expansion foam for the given size. Won’t buy this brand again

Isn’t easy finding a 20×24 pack.
Did a good job keeping my computer nice and secure in box.
Lost a couple packs in shipment, but I bought more than enough.

PRODUCT THOUGHTS:
These kinds of mailers are really neat if you’ve never used them. You basically pop two sections together and then that causes a chemical reaction to create the foam. This works great for things that are fragile like you see in the product images. Glass, Electronics..etc. All of that. Especially PC parts, which I tend to sell from time to time, so these kinds of foam bags are really important for me. They are not that big before you use them, so they don’t take up much space while you have them stored away.

These guys worked just fine for me. They were very simple to use. I didn’t have any faulty packs like some others did. That’s very unfortunate for them. But as long as they arrive properly, you won’t have any issues. I think the cost could go down a little bit in my opinion, but other than that I Can Recommend it.

The foam doesn’t expand much. It protected my items for moving but you cant shape as well as i have seen other brands.

This is a great way to protect things, if the price is right.Pros When not activated the packs are really smallAllow you to protect the top and bottom of an entire itemCustom fits to your boxProtects things really wellCons The price is a little tough, you need two per shipment, so you need to be willing to spend three twenty five x 2 to protect one item.Since you only get 8 in one pack or 4 in the smaller, you may be worried about following the instructions well enough on the first try.Overall this is a great way to protect something important, but it’s a little too pricey for every day shipping of lower end items. If 6.50 is worth protecting your item I think this would be a great fit.
