was easy to use for putting around pipes coming out of fridges

This is a perfect solution for sealing small and irregular gaps because it is easy to apply and non-permanent. One can reshape it weeks or months later, or remove it altogether. Non-toxic and safe, many thanks to my sister who researched it for me.

Wow, wish I had known about this product before! I purchased it after searching for a way to seal a draft coming in around an interior water pipe. The stickiness was very good yet it was easy to work with, and it took care of sealing out the cold air coming in around the pipe, I highly recommend this.

I installed a whole house humidifier (it's dry here in Colorado in the winter) on my furnace and wanted to seal the outside and a certain AI assistant recommended this stuff. It was a good call, I rolled it with my hands into cylinders and put it around the humidifier and the seal is solid and seems like it will last a long time. I am very pleased. It's sticky but not super sticky, pliable but seems like it will stay in place. It doesn't smell much (if at all) and I washed my hands with soap and water and most of it came off with minimal effort.
