I was disappointed that I had to buy a pack of 4. I would have much rather bought just 1 stick because I don't use it that much and I definitely will not be needing all 4 for a good number of years. Why can we no longer buy them singly? This seems wasteful - also if single they wouldnt need to be packaged. Why so much packaging? That is my comment.
Scouts used it for project gluing smaller cut paper to larger sheet. Glue stick did not glide smoothly and often came out clumpy leaving bumps or paper tore as the glue stick was applied.
A Friend of mine had a glue stick for envelopes only. I liked it so much I went into Staples looking for it. It was made by Ross. When I asked about it I was told that Staples did not carry a glue stick for envelopes. I was recommended this product which is basically the same thing.
