I purchased a well built Miseno medicine cabinet which comes with 2 fully adjustable glass shelves. I purchased it with the intension of adding an extra shelf at the bottom, assuming it should be a simple process to request an extra bracket and shelf. However, I soon found out that Miseno does not sell shelving accessories. I have looked through all the hardware stores and Amazon but am not able to find a bracket that matches the one provided by the manufacturer. (see attached photo) Please let me know if you have any information on where I can find this bracket. As an alternate solution, I have found some self adhesive shelf clips I can use but am not sure how effective they are in the long run. Will appreciate any helpful suggestions you can share. Thanks,
