Product review (5 stars): Great for disposing of grease from foods and more!
I started using these when we had a travel trailer and I needed something to put the grease from food in.  They hold the grease easily and when ready to dispose of  just seal and toss.  Couldn't be easier.  I use them in my home as well to avoid clogging up my kitchen sink.  I also use them for things other than grease that I don't want to pour down the sink.  These are great and have many uses.  The bags are heat resistant and I have never had one leak, ever.
Highly recommend.
