Just hang these super-handy storage sacks over the back of students’ chairs to put essential supplies right within reach…and keep children’s desks clutter-free! The sturdy nylon sacks each have two easy-access pockets—including a small pocket on top for small supplies like scissors and pencils, plus a big, reinforced pocket below for heavier books, notebooks and more. Regular sacks measure 15"h x 16 1/4"w; fit our 7 1/2"-13 1/2" plastic chairs and most classroom chairs.
