One point to beware of: We have used anti-reflective materials and the
resulting reflections,
while greatly reduced, are with some products sometimes coloured.
Because coloured reflections are unexpected, they can be obtrusive.

Rather than trying to reduce the reflection is it possible to attack
the problem from the other direction? For example can you increase the
brightness of the lighting of the objects in the cases, or can you
reduce the lighting that is making the reflections?

Feel free to contact me directly if you would like help with the
problem.

With best wishes,

Mark Sutton Vane.
