This is the Tran Natural Canvas Artist Paint Brush Roll Up, a brush holder, or brush wrap.
When I received it, I was quite surprised by the large size. When opened flat, it's almost twice A3 size.
In the photo above, I've put a small pencil for size comparison. The longest brush I have above is 32cm, and that extends beyond the halfway mark of the brush wrap. It's not an issue because you can just fold anywhere above the brush hair. The other brushes are around 24cm and shorter.
The canvas used is quite thick and certainly very durable. It may be a bit stiff but it's a non-problem. When you fold it up with brushes inside, the overall size can be a bit bulky. The stitching is also well done. Outside, there are two strings for tying to keep everything in place, so there's no way brushes can fall out.
The pockets are quite big. In some pockets you can certainly fit two or three brushes. In the photo above, I've 12 brushes fitted, and there's still space to hold smaller brushes.
I don't think you can go wrong with this brush wrap. It's made to last. Good buy.
This is how it looks with my twelve brushes inside.
