Abstract: A multi-segment writing implement has a plurality of a cylindrical, nested-stackable writing implement segments with different writing elements attached thereto and which connect in various combinations to form a writing implement with various writing elements on the ends thereof. A first type of writing implement segment has a writing implement and connector on one end and an opening and attachment collar on the opposite end. The opening communicates with a hollow cavity to allow nested stacking of the segments. A second type of segment has a connector on both ends and a writing element on one end. The attachment collars and connectors of the segments are configured for releasable, frictional nested connection of adjacent segments. Either end of the segment of the second type can be connected to the attachment collar of a first type of connector, thus providing a large number of possible configurations of the multi-segment writing implement.

Abstract: A carrying case which can be opened or collapsed is disclosed. The carrying case has at least a first nestable module and a second nestable module. The first module has a bottom portion which has an inward projection. A side portion of the first module has a compartment which can be withdrawn from the first module. A second module has a top portion which has an outward projection and a side portion of the second module has a compartment which can be withdrawn from the second module, wherein the outward and inward projections of the first and second modules cooperate as a stop means for controlling the opening of the carrying case. The first and second modules are nestable within one another and are adapted to slidably collapse into one another and slidably open into a position to provide access to the compartments.
