A stand for holding and sealingly retaining a plurality of India ink drawing implements includes a like plurality of sleeves for holding the drawing implements and for sealingly retaining the implements to prevent India ink therein from drying. Each implement comprises a tubular drawing point, a grip having a front end to which the point is attached and an annular bid of the grip rearwardly of the front end. A tubular packing in each sleeve surrounds the drawing point and has an annular sealing lip at an end thereof remote from the drawing point. A packing insert in the interior of the packing has a plane face adjacent the drawing point. A tubular clamping element in each sleeve surrounds the grip adjacent the packing and has an inwardly projecting cam. A first spring biases the packing insert to press the plane face thereof against the drawing point and a second spring biases the annular sealing lip into contact with the front end of the grip while engaging the annular bead of the grip with the cam whereby the drawing implement is doubly sealed and retained.
