Tape mark

When you use tape to stick something to something else, sometimes when you take the tape off, it leaves a little mark or sticky residue behind. This mark is called a "tape mark." It happens because the sticky stuff on the tape sticks to the surface it's on and when you take it off, some of it stays there. This mark can be annoying because it might not come off easily and can make the surface look dirty or not smooth. So, it's important to be careful when using tape and make sure to remove it gently and completely to avoid leaving a tape mark.
