This edging is the perfect thing to finish off your peel and stick tile project.
However, learn from my mistakes, it is extremely hard to cut, I could not cut it with the knife purchased off this site, I had to use a Stanley knife and even then I struggled to get a straight edge. When I was at Bunnings after the install to get silicone, I found the perfect knife set that has a flat edge (like a screwdriver) and used that to trim one piece i hadn't stuck on and it worked perfectly. Highly recommend getting some kind of knife that is wider than the width of the trim, that you can just push down and make a straight cut through the trim.
My next mistake was pulling the trim to tight to make sure it was straight on the wall when applying it and it retracted overnight and now i have visible gaps at the joins, unfortunately I don't have enough trim left to pull off the parts that I need to, to reapply and fill the gaps, so i will try to superglue them so the white wall doesn't show through the corners.
I also wouldn't recommend this as 'renter friendly' when sticking on top of paint, like the tiles, when I had to lift to straighten, it took paint off the wall.
UPDATE: have had to order another roll and some of the edging was coming unstuck. The sticky foam stays on the wall, but detaches from the black edging it's self. See last 2 photos, this happened to 4 out of 6 of the lengths I attached.
It has also shrunk, leaving bigger gaps than those shown in the photos.
