Comments about Staples 9''L x 4''W Acrylic Shelves For Pegboard:
Not sturdy enough for all but the lightest, centered items - use as a shelf. It takes a bit to put product balanced - then all it would take is for customer to remove the item and try putting it back to unbalance it. Would be easy to knock and dislodge the item on the shelf. I'm using these, but a bit disappointed. I MAY recommend to a friend as they are functional, and I could not find similar. Maybe the larger size might work better, but reluctant to try. HOWEVER - I was not putting a shoe on it, as advertised, and it MAY be perfect for this, as it's a balanced item and doesn't need much to be placed centered.
