Multi-tier portable storage case in the style of a Boby Trolley or modern art supply box

This item is a black, multi-tiered portable storage case constructed from molded plastic (likely ABS or a similar polymer). The item features a vertical, rectangular main body with an integrated handle on the top surface. It utilizes a cantilevered or pivoting drawer mechanism, with two visible open compartments: a shallow tray with multiple internal dividers and a deeper square bin divided into four sub-sections. The design appears stylistically consistent with late-20th-century Italian industrial design, particularly pieces like the Joe Colombo Boby Trolley, though without visible markings, this remains a hypothesis. The exterior showcases a matte finish with some visible surface scuffs and light scratches consistent with regular use. The hinges and pivoting arms appear to be integrated plastic or metal pins. No visible logos, brand names, or manufacturer stamps are legible in the provided image. This type of modular storage is commonly used for art supplies, drafting tools, or cosmetic organization and is estimated to be modern or late-20th-century in style. The craftsmanship suggests a functional, mass-produced utility item focusing on space-efficient organization.

I have examined the images of this multi-tiered portable storage case. Based on what I can see, the item is a molded plastic utility unit featuring a cantilevered drawer mechanism. The design is stylistically consistent with late-20th-century Italian modular furniture, such as the Joe Colombo 'Boby' trolley; however, without visible manufacturer stamps or labels, I am treating this attribution as a hypothesis. I cannot verify from a photo whether this is a production by Bieffeplast or a later 'in the style of' reproduction. The value of $150-$350 reflects the market for a verified vintage designer piece in good used condition. If this item is found to be a modern unbranded replica or a mass-produced copy, the value would likely decrease to a range of $40-$80. My estimate is based on the matte finish and visible surface scuffs, which suggest regular use and diminish the value compared to a pristine example. The current market shows a steady demand for mid-century modern and space-age organization tools for both studio and domestic use. To confirm the higher valuation, an in-person physical inspection is required to search for embossed manufacturer marks on the underside or inner trays and to verify the quality of the pivoting hardware. Provenance documentation or original retail labeling would also be necessary to move beyond my current hypothetical attribution. The final value is contingent upon this authentication; unauthenticated pieces generally sell for significantly less than those with a verified production history and designer pedigree. Final value is dependent on whether the materials are high-grade ABS polymer or a less durable contemporary alternative, which cannot be determined through photography alone.
