KOH-I-NOOR adjustable drawing tube 60–110 cm length, 8.5 cm diameter (model 174750)

The KOH-I-NOOR adjustable drawing tube (length 60–110 cm, diameter 8.5 cm) is a rigid, extendable storage and transport tube designed to protect rolled drawings, plans, posters and artwork. Its telescopic design allows the tube to be shortened or lengthened to fit different document sizes while the solid construction resists bending and crushing during handling and transit. A removable end cap secures contents and provides quick access when needed.

Advantages

The adjustable length provides flexibility for a range of document sizes without requiring multiple fixed-length tubes. The rigid body helps maintain the flatness and integrity of rolled media, reducing the risk of creases or damage. The compact closed length makes storage simpler, and the screw- or snap-style end cap keeps contents secure during transport.

Suitable for

• Architects and engineers transporting project plans and blueprints
• Artists and illustrators carrying large-format artwork and posters
• Students and designers needing safe storage for presentation materials
• Photographers and print shops shipping rolled prints

When it may not be suitable

This adjustable drawing tube is intended for rolled media and will not accommodate flat, rigid boards or extremely large canvases that cannot be rolled. It is also not designed as a waterproof, submersible container; while it protects against light moisture and physical impact, it may not fully prevent water ingress during heavy rain or immersion.

Key specifications

• Adjustable length range: 60–110 cm
• Inner diameter: 8.5 cm
• Material type: rigid tubular construction (protective tube)
• Closure: removable secure end cap
• Function: storage and transport of rolled documents and artwork

How to use

Slide the end cap off to place rolled drawings or posters into the tube, then adjust the outer and inner sections until the tube length matches the document. Reattach the end cap to secure the contents. For transport, carry the tube by hand or fit it into a larger bag; when not in use, collapse the tube to its shorter setting to save space. Avoid overfilling beyond the diameter and ensure tight rolling to minimize movement inside the tube.

What to consider before purchase

• Measure the longest rolled item to ensure it fits within the 60–110 cm adjustable range
• Confirm the 8.5 cm diameter accommodates the tube size of your rolled documents
• Consider whether you need additional weatherproofing or padding for fragile originals

Usage recommendations

For best protection, roll documents with the printed or drawn side outward to reduce edge curl, use a protective inner sleeve for delicate media, and secure the end cap before transport. Store the tube vertically in dry conditions to prevent prolonged pressure on any single area of rolled contents.
