Remo  Pre-tuned Frame Fiberskyn Hand Drum 2.5"  X 12" Inches HD851200 NOTE:  No defects - Theses drums are for recreational music making such as for Drum Circles.  They are pe-tuned.  You cannot tune them.  I would suggest these for a novice, not for a professional drummer.  These are the types of drums you would pass out to people in a drum circle type setting.  Maybe for people who have never played an instrument before.  They are good for "Call and Response" and rhythm exchange.
