By the same token as the Restickable Glue Stick, 3M’s Scotch makes a product called Removable Magic Tape which I use extensively in doing rough page layouts of books with a lot of graphics on each page. It sticks to paper or just about any dry surface. Pulls off easily, leaves no residue. Unlike the regular Magic Tape, you can easily pick it up and move things around. I’ve been using it for over 10 years and find it’s less messy and way quicker to use than the glue sticks. If you already have the Magic Tape dispensers, the removable refills come in a blue box (Cat. # 811).
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
