Compliment slip & DL envelope storage box — frequently asked questions
What are the dimensions of this box and what does it hold?
The box measures 231 x 121 x 57mm externally and 226 x 116 x 55mm internally. It holds compliment slips (99 x 210mm) and DL envelopes (110 x 220mm) flat in a single stack. The internal dimensions also accommodate DL-format printed materials, folded A4 correspondence, and other print media of similar dimensions.
What else can I store in this box?
Beyond compliment slips and DL envelopes, this box is widely used for DL-format brochures, folded A4 letters, presentation inserts, and other slim printed media that needs to be kept flat and protected between print runs or during client delivery. Its long, shallow format also works well for storing pens, pencils, markers, and other stationery in an office or studio environment.
Is this box acid-free — safe for archival storage of printed media?
Yes. The box is made from acid-free polypropylene, which means it will not react with or damage printed media, paper, or card stored inside it. Safe for long-term storage of print jobs, presentation materials, and client delivery packs.
What material is this box made from?
The box is made from PP5 polypropylene — a chemically inert, recyclable plastic that is acid-free, moisture-resistant, and durable. Available in clear transparent for instant content identification, and TOUGH high-impact opaque white for more demanding environments. Consistent production run dimensions ensure uniform appearance across large orders.
Where is this box made?
This box is designed, manufactured, and quality-checked at our factory in Sunbury-on-Thames, Surrey. S.B.Weston Ltd has been manufacturing precision injection moulded products in south west London since 1948 — originally from a factory in Teddington, then on Platts Eyot, a small island in the Thames, before moving to our own factory premises in Sunbury-on-Thames in 2002. When you buy a WestonBoxes product, it is genuinely made in Britain — not just branded here.
