Since I've had these boxes I've never had a frame damaged. I've
shipped hundreds of pastels under glass by rail, truck and bus and
never broken any glass or had the pastel dust come off onto the
glass. The size of the box should suit your painting but the box
should be wide enough to stand up by itself, this particular box
will take three paintings.
