What are the problems for balsa wood?

Answer 1

Assuming you mean positive attributes, it is good for carving and crafting, with a chisel or dremel. It is a soft wood, thus making it easy to cut, but obviously easier to break. It's soft enough to make a slight indent when you press your nail against it relatively hard.

Answer 2

Unlike other hardwoods, balsa wood cells are fatter and contain more water. Only 40 percent of the wood is actually solid because it contains less lignin - the plant "cement" that solidifies wood. It is considered the lightest and softest of the hardwoods.

Answer 3

It has a tendency to dent

Answer 4

You can bend it
