My daughter grew up too fast and got caught the corner of our dining table. So I bought the foam tip. They are fixed with double-sided tape supplied with foam corner. And held without problem. They are darker than the picture which suits me very well (my table is wenge color and corners foams too). Established for 3 months, and no worries, they remain perfectly stuck. My daughter took the edges of tables 2 recovery since and had no trouble at all, not even a tear. She was as surprised as me to have nothing.
