15" x 18" 2 PCS Instant Pack Quick Expanding Packing Foam X-100 Bag for Packaging and Shipping

Trip to the hospital and hours of clean up later its safe to say I regret ever finding this product. Foam package exploded into my eyes which I require more appointments with an optomitrist to judge the damage. Went all through the PC and all over the floor and walls. Use other brands stay away from this one.

Used a few of these when moving, to protect my computer tower. They worked great! After a two thousand mile drive across the country everything was still in one piece and the foam remained as stiff as when I first set them up. Would definitely use again

Used these multiple times for my pc. Put them on the inside and had it shipped from AK to VA and didnt break my pc at all! Was easy to use, great quality and they were pretty cheap.

Did what it claimed. Caution, watch videos. Expands very quickly after mixing. You have to be ready to insert your cargo. Purchase oversize of your box as its flat dimensions shrink as it swells.

These work just fine. You do need to be careful when you pop the left internal bag. I didn't have a problem, but I can understand someone having an issue if the apply pressure on it that directs it contents upward instead of to the right. You pop the left bag - I used my fist and rolled my fist from left to right to push the contents to the right. I repeated the same things on the right side except my fist roll was right to left. Once I knew that bags had popped, I just changed sides the 15 to twenty times they tell you to do. The bags to get pretty hot, so I had a thin wood panel that I could use to keep the top level in the box. Now, the real detail - I used the 18' x 18" bags, so what you get is a smaller size that has some height. A rough idea is the 18 x18 did a 15x12x3 volume. The more you press down, then you will get a lower volume. I am working on a 40x12x12 box that contains two pieces of ceramic artwork. They are long and can sit side by side in the foam. It will take 12 of the 18x18 bags to fill the box to the top. The product certainly doesn't do as well as the commercial machines, but the price it definitely lower doing it yourself when when you have to use 12 bags.
