Blueprint Holder 2 Pack 32-Slot Roll File Organizer - Classroom

In this review of the PerKoop 2 Pack Blueprint Holder, the bottom line is simple: it is a practical, low-cost storage solution for anyone who needs organized long-format papers. The reviewer found these corrugated cardboard boxes especially useful for teachers, architects, and home office users who store posters, anchor charts, blueprints or maps up to 31 in tall. The single biggest reason to buy is the 32-slot compartment layout across two boxes, which makes it easy to sort and retrieve rolled documents while keeping them protected from bending or light damage.

Key Features

• 32 Slots: Two boxes provide a total of 32 compartments, so different plans, posters or charts can be stored separately for quick access.
• Compact footprint: Each box measures about 31 in x 14.2 in x 14.2 in, offering tall capacity without using excessive floor or shelf space.
• Individual compartments: Each slot is approximately 3.54 in x 3.54 in, which helps prevent rolls from unravelling and makes each drawing easy to locate.
• Corrugated construction: The cardboard material is sturdy and firm, providing protective support while remaining lightweight for handling and moving.
• Writable labels: Tables printed on the side and lid allow for recording file information so organization is faster and more consistent.
• Quick assembly: The boxes are easy to put together from flat-packed form, which saves time when setting up multiple units.

Who It's For

These blueprint holders suit classroom teachers, small design firms, contractors, and home office users who need to store rolled documents such as anchor charts, posters, plans and maps. The dual-box set is useful where multiple categories or projects must be kept separate without specialized shelving.

People who need weatherproof, permanent archival storage or heavy-duty plastic bins should look elsewhere, since these are corrugated cardboard and best for indoor, dry environments and moderate handling rather than continuous outdoor or industrial use.
