Expandable Foam Bags 2 Packs 16" X 18" for PC Packaging, Expanding Foam Packaging Material & Shipping Foam

Shipped fast, it worked as intended to pack fragile item (glass). You have to lay the bag flat on the floor, press the Left side until you hear/ feel a pop, then press right and left (marked area) back and forth to mix throughly. The mixture will then explode inside the bag and u have to spread it evenly quickly, then place in box to harden, after spreading it out evenly I placed it in the box and closed the box and held it down until I felt it was hardened enough so it fills up the box and did the other side same way. You should have everything ready to go as you have to work quickly!

This is a great packing material to protect an item for shipping. The expanding foam forms to the item to protect it during shipping. I used one on the bottom holding my item down in the foam as it expands. Then when the foam is set I used another one which I laid on top and closed the box lids and held them down to make the foam form around my item. After a few minutes you're done. Unfold the lid remove your foam and check out what you did. Perfect, my item wasn't moving anywhere, it was locked in foam all around. One TIP: pre-plan what you're going to do. Once you break the pouches and mix up the foam (per instructions) you need to move quickly as once it starts expanding you don't have much time. This stuff is perfect. That's the way to ship anything you don't want bouncing around during the rigors of shipping.

This product was used to package an irregular shaped sculpture for moving So far so good, will check and see after the move.

Used it to ship a computer overseas without a GPU Holder. Just those the 2pcs in a pack. It secured it very well.

Wish I could give zero stars. I followed all instructions to a tee. The first pack outter bag broke and air was coming out. Thankfully no chemicals had released. I still threw it outside just in case. I thought maybe it was just a bad bag. The second bag popped as well releasing chemicals into my kitchen. Currently airing out the whole house and making sure I do not have any severe reactions or complications. Completely unacceptable. I will be contacting the company. Use caution if you plan on buying this product.

I bought these ready to ship a small ITX system... and didn't realize just how thin that bag wall is. as it expanded the bag popped and turned a REALLY nice system into a 400 usd mistake. I won't be buying some of these and if you do find a smaller size this is just too cheaply made.

One of these was perfect for transporting my mini-ITX cross country. I just needed something to fill the space after I removed the graphics card while in transport. Warning: after you pop the internal bag (which was a little difficult) and you need to mix it together to create the foam reaction, the chemicals inside do get hot.

Seems to struggle to fully fill bag when contorted over PC parts, this may be user error.

Not easy to use when when inflated does protect fragile items,they worth the wait.
