This is a great way to show the climber in your life that you love them. The largest hold has a medium sized jug and a cobble sloper on it which is great for boulder problems. The remaining holds offer positive grips of all varying rounded incuts that are very comfortable and easy to hold on to by children. They are designed so that when bolted on to look like a heart, they are in the easiest position to hold on to. For the more skilled climber, flip them upside down and each hold has been designed to be a pinch. On a steep 45 degree wall, these holds are in the V3+/5.10 range when set close together.
