    They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.

    Really good wall amounts. I used the drywall anchors and it feels sturdy. I put like a 3 pound Crystal on it and it’s holding perfectly fine. I also was able to paint them with no problem would buy again.

    Beautiful shelves!
    Size: 48 Inch, Color: Natural, Size: 48 Inch, Color: Natural
    Since new build homes typically don't come with towel rods this was what I envisioned instead. I purchased the hooks separately. The shelves are perfect! I ordered a 36in set as you see with the cream towels and a 48in set that you see with the green towels. They're not loose but not 100% sturdy. I recommend maybe gluing to the wall in addition to the rest and definitely screwing into a stud. They're easy enough to figure out without the instructions. But I will say they're supposed to be screwed in underneath to the rods but they did not come with an appropriate screw for that so I had to use some I already had on hand.
