Hello Ben, This is Matt - builder of Pipette kits.
To make sure we are on the same page... Are you talking about the black plastic brackets for the inside corners of the Pipettes? Or the wavy plywood brackets on the inside sides of the sides? If these I should have glued them in at my shop.
Please let me know and feel free to post a picture or text me one at 2O6 849 65eight4. Sorry about the problem. We will figure it out.
Thanks,
Matt
