I honestly don't know what I'd do without this handy and easy to use tool. It is the perfect way to apply adhesive to small embellishments. I have used it to apply adhesive to die cuts, punches, plastic embellies, ribbon and rick rack, thin strips of paper, even buttons (thin ones)! The 150 is limited to small items, but when it comes to those small items that are difficult to apply tapes to, it is truly indispensible. You can purchase permanent or repositionable cartridges for it, and the cartridges are very easy to replace, just pull the old one out and click the new one into place. I would recommend this tool to all crafters.
