A pack of size 25 write on Easy Grip bags made from polythene with a grip seal / zip-loc seal across the top, 250 x 350mm or 10" x 14".
This Grip Seal Bag is great for portioning up dry goods like pasta, rice and flour. 3 write on strips on the front of the bag make identifying the contents easy. Tested with a Biro, Rollerball, Sharpie & Pencil. Large enough to hold an A4 sheet of paper. When sealed, the bags can be stored in the freezer, but are not microwave safe.
Easy to recycle afterwards, grip and seal bags can be reused (with a little care) and can help prevent perishable goods going off so quickly.
