I agree with reviewer Jill, this is one of the most functional gadgets in my kitchen. I use them every day. I have 2 sets, one black & one white, and I just ordered a 3rd set in multicolor. They're great for all kinds of food bags: coffee, cat food, cereal, pasta, rice, anything that comes in a bag. I have one on my front door to hold notes or letters to be mailed. I have one on my refrigerator for notes & grocery lists. I use them in my home office as giant paperclips to hold stacks of papers. I use them in the bathroom on bags of cotton balls & other supplies. There seems to be no end to the uses!
