I remember when I was working in a bakery in Italy, where I am living, I made this piped biscuits (or in Italian - biscotti at least twice a week. We often dipped them into chocolate then stored them in transparent jars. They look so nice. Everyone loves them, especially children.
It is not difficult to make this biscuit, but it is highly recommended to have a big or huge tip for your piping bag to make sure the content can be piped easily. The room temperature should be around 19 - 21 degree celsius to make sure the dough doesnt melt. :)
