A self-adjusting storage rack for holding vertically stationery, envelopes, letters, file folders, cards, photos, magazines and similar flat surface articles. The device comprises of two upright ends mounted on a base of two flat telescopic rods; a third central telescopic rod acts as a guide for a elastic, expandable and continuous multi-coil; each end coil is attached to an upright end so that one upright may be manually pulled out, extending the length of the rack to the full length permitted by the telescopic rods or any length in between. The elastic coil between the two uprights adjust itself accordingly.
