Zig 2-way glue pen
I saw the Zig 2-Way Glue Pen at Walmart and decided to try it out.
The way it works, is it goes on blue, then dries to clear within a few seconds. If the glue is sell blue when you attach your embellishment or other piece of cardstock, then it will be permanent.
If the glue is clear, then it will be removable. I have found that it doesn't really have a good strong hold for cards, but it's not a complete waste of money.
The pen can be used to re-stick your un stick Cricut mats. All you have to do is rub the glue pen down the mat a few times, then wait for all of it to turn clear.
Also, they can be used when attaching loose glitter to projects. The thin tip really works well for this. You just simply draw the image you want glittered, then sprinkle it on. The glitter sticks really well even after the glue has turned clear.
