Bound with a black wire-o ring, Wire-O Sketch Books feature heavy-duty gray binder covers and alpha cellulose, acid-, chlorine-, and lignin-free sheets that have an extra layer of padding compound to assure long service and resist tear out. Each sketch book contains 55 sheets of 130gsm paper that accepts dry media, light washes, markers, inkjet and more.
The large black wire-o rings accommodate the expansion of pages which have been worked, and the 2mm binder board front and back covers form a rigid surface which functions as a drawing board.
