The first time I used this glue pen, I wasn't sure what to expect. Would it flow nicely, would it hold, would it bleed through??? Well, let me share my findings. Yes, yes, and no! It flows so smoothly, it holds beautifully, and it doesn't show or bleed through the paper. It's the perfect tool to get into teeny tiny areas that need a dab of glue. I highly recommend this.
