If you're familiar with the ATG then you know how much of a time-saver it is. For those who do a lot of crafting or have big projects and hate having to run to the craft-store to but overpriced refills, this is the perfect solution. You know you're going to use it and it's not going to go bad so why not buy it in bulk and save a TON of money. Each of the rolls is individually wrapped and fits perfectly into my ATG and I expect these to last me a good long while through many craft sessions. Loading is simple and the adhesive sticks firmly. What more could you ask for?
