SELECTION EXPERT ADVICE

Shipping and Mailing for Office Operations
MORE INFO
Office mailrooms process outbound correspondence, packages, and interoffice shipments across a wide range of sizes and weights. Having a core selection of standard envelope sizes, padded mailers for fragile items, and small corrugated boxes for equipment shipments eliminates the need to improvise packaging for each unique piece.
Organization and Labeling for Schools and Offices
MORE INFO
Label systems for file rooms, storage areas, classroom supplies, and office equipment rooms create the organizational structure that allows staff to find what they need quickly without assistance. Consistent label formats and color coding across departments reduce administrative overhead and make audits and inventory counts significantly faster.
Moving and Storage for Office Relocations
MORE INFO
Office relocations and classroom reorganizations require significantly more boxes, tape, labels, and protective materials than most administrators plan for. Building in a 20% buffer on box quantities and ensuring you have both moving-weight cartons and file-storage boxes on hand prevents the delays that come from running out of supplies mid-move.
Overview

4,961 office and education supplies: spiral wound mailing tubes with caps, polyester laser labels, 2.2 mil carton tape, moving boxes, bins and dispensers. Sizes and case counts are on every product page. Orders ship from five US regional warehouses; for mixed or recurring orders use the bulk quote path with SKU, quantity and destination ZIP.
