A Good Solution for Rough Edges of Wood.
Color: Birch, Size: 1"x 25ft, Color: Birch, Size: 1"x 25ft
This is a great product. We needed to recover the booth in our motorhome because the faux leather is peeling. The booth is made of plywood and has rough edges. We opted to cover the booth with heavy wallpaper, but needed something to cover the rough edges. This product is really affordable and very easy to use. It adheres pretty well. We had planned on painting the wood veneer edging, but we decided that the wood tone fit right in with the rest of the trim in the motorhome so we left it raw. While I bought 1" because that is mostly what we needed, some other areas were only 3/4" wide. It was so easy to run an Exacto knife along the extra edge and trim it smoothly.

You get what you pay for. Won't order again.
Color: Birch, Size: 1/2"x 100ft, Color: Birch, Size: 1/2"x 100ft
Inconsistent width, and soft glue. The veneer is so thin you can see the plywood layers under it in places. The 1/2" width varies from 0.55" to 0.45" and was too narrow to cover the edge of my 0.46" plywood in spots. Even when fully cooled (left some pieces overnight before trimming) the glue is soft and tacky, and loads up on the edge banding trimmer blade. I was able to cover all my pieces, so I still gave it 3 stars. But I won't order it again. It's not worth the couple of dollars I saved. I also ordered a roll of 3/4 and threw it away. Same issues, and the color was way too light (looked more like raw maple than birch)
