JetMaster Display System was featured on AP Testbench. Here is what Tim Coleman said:

ThE JETmasTEr
Display System offers a
cost-effective and simple
alternative to a canvas print
stretched over a wooden
frame. It is a lightweight
and tough flat-pack base,
made from a pre-cut, pre-laminated,
corrugated-board template that folds to create a
frame box. By using a ruler, cutting mat and Stanley knife, and
following the clear instructions, the process of fixing a canvas print
to the adhesive base and then folding over and fixing the edges
for a completed frame box took me a few minutes. The wrap
should not sag (unlike many wooden-frame canvas wraps)
and is light enough that it can be hung using a single tack.
I found the wraps are best suited to canvas inkjet media, so make
sure your home printer can accept this.
If it does not, then this option will not be
cost effective. Photo and fine-art papers
can be used instead, but they do not fix to
A simple, tidy and
the adhesive as effectively and the surface
cost-effective
of photo paper is much less durable than
gallery wrap
canvas. For wraps that have print over the
folded edges, there will be clipping from the
edges of the print area. Sizes available range
from A4 to 16x20in. Tim Coleman
