single block size 15*3.5*4cm 

The Cylinder Blocks is a classic piece of Montessori material, and this set is simply a smaller version of it.  As in the regular set, the mini set includes four blocks with pieces that vary in height  and/or diameter, but the mini set has only five pieces in each block where the regular set has ten.  Made of clear beechwood with a satin-touch finish, each block measures 15 x 4 x 3.5 cm.
