A full roll is a much better value but this product is much more convenient

You could make your own from a larger, less expensive roll, but I think the cost of these small roles is a better value than the time and hassle associated with making your own - we all know that pulling duct tape off a roll is not easy, and, in my experience, it is extremely difficult to reroll it tight and straight - so don't bother unless you have way more time and patience than money...

what can I say, works as it should and is a great size to add to your cars road side emergency kit
