Economy A1 Art Portfolio Case - Artist Storage Bag - Multifunctional Weather Resistant Portable Carrying Case w/Handles for Paintings, Presentations, Sketches - Black (35.1" x 26" x 1.7")

does the trick!

Good generous size.. however would prefer a zip either side that meets in the middle rather the one..

Keeps art work well protected and value for money also good quality

It does the job after a fashion, but has some distinct downsides.:1. It will only just take an A1 sheet with very little space to spare, and it's necessary to manually ease the zip over the corners of an A1 board, so it's clear that the corners will not be well-protected.2. The sides of the case are not sufficiently rigid to enable it to stand up by itself. If set down on its long edge it will simply fold in half unless the contents are rigid enough to prevent it. This makes it very difficult to load unless one has sufficient space to lay it down flat. It's also the inverse of what one expects - the case should protect the content, not vice-versa.3. The long zip that goes around the 3 sides has only a single slider, which means that to find the slider to open the case, on has to fiddle around at ground level to find which corner holds the slider. This is pretty inconvenient when opening and closing the case.4. The handles are thin and sharp-edged, making the case quite painful to carry if it contains any significant weight.Overall, I find this item represents pretty poor value for money at the price I paid for it (£35.95). The day after it arrived I found a better item (specifically, one that resolved ALL of the points made above!) for £20 at a local bricks 'n mortar store. This case will be returned to Amazon.

Really good quality and great value for money. Carries quite a bit of artwork and is not too heavy. Has a strong sturdy strap that came with it.

Very pleased with this product. Allowed me to keep all my designs and drawings in one place for convenient, tidy storage

It did what I wanted. Not the best quality but not too bad either

Very pleased with this purchase. Good value for money and quality.
