When I searched for refills for my 3M ATG, this was the recommended product which I ordered. On receipt, the package says "Do not use for antiques, heirlooms, valuables or irreplaceable items."
Nowhere in the product description on the website does it say that it is not the same acid-free tape I had purchased previously, nor was the acid-free tape recommended for me. I also ordered scrapbook paper and embellishments. Purchase at your own risk!!!!!
