S648. Sakura Quickie Glue Pen. 0.7mm, Pinpoint roller tip.
This versatile tool is almost like a ball-point pen with glue in it. You can write with glue or add a little line of glue here or there. Works extremely well with glitter. Works, too, with embossing powders and Pearl Ex and similar products. The glue has an extended wet time, so you have a good amount of time to work with it. When the glue is wet (blue in color), the bond will be permanent. When the glue is dry (clear), the glue is slightly tacky, so the bond is removable. Has a special cap so you don't confuse it with other pens. From Sakura.
