Hi, I would like to know the price for Command Damage Free Picture and Frame Hanging strips, Large (8 Pairs). I am interested in buying 1 Bag/Bags. Is this authentic 3M products? What's the size of the strip? Is it 3 5/8 X 1/2 X 1/10 Inches? Is it US$0.1 for 8 Pairs (16 strips)? Does the price include shipping? Thank you. Please provide us with a quotation. Thank you.
