I love these! Underneath my sinks used to be a huge mess because I would just throw everything under there. These give everything a place and make organizing so easy. They are also incredibly easy to assemble. You just take the metal rods, adjust them into the holes, and stack the next tray on top. It takes less than 2 minutes. As shown in the pictures, you can fit nearly 4 Cerave bottles in one tray. Although they are clear acrylic, they feel to be good quality. They come with small pads to put underneath the rods so that there’s no chance your cupboards will be scratched. I used them in my bathrooms, but will probably order another for my kitchen!
