I had a bit of trouble getting the cap to puncture the seal on a couple of disposable tubes, leaving some glue on my fingertips at the end, but it came off with nail polish remover. I've put a pair of slippers in the washing machine and all the edges of the rubber sole have since ripped and are still attached at the stitching, but are quite "wobbly" when walking. I used glue to attach the soles of both slippers and it worked great, it formed a seal very quickly (a few seconds) and I wear them now and they are fine. I am very happy with this glue and will reorder when it runs out! Disposable tubes are good because they contain no waste. This product is made by Elmer's Glue so you know it's a trusted name. Buy with confidence when you need super glue!
