The Ortega RUPA5 Pineapple Ukulele is a concert ukulele. The side and back are made of sapele wood and the top of spruce. The decorations on the top are laser-burned. The RUPA5 Pineapple has a nice full sound due to the pineapple shape of the sound box and the concert size. Super cool ukulele for anyone who starts or plays for a while and is looking for a model that conveys the tropical feeling and is just a little different from the others.
