This is the Deluxe Semi-Hard Cello Case.  It offers the protection of a hard case in a beautiful rounded shape with a material black finish.  It is a combination of exterior padding, hard foam and soft interior padding. 

Everyone wants to protect their child's instrument but doesn't want to buy a new case every size.  This problem is solved by using removable blocks so each case can fit two sizes.  They come in 1/4-1/2 and 3/4-4/4.
