Fits perfect by my sink. All my items worked in there. The only thing is I had to use zip ties to hold bar on for hanging my dishcloth.

Clean Look and Practical — Keeps Sink Area Organized
Color: Black
I’ve been using this HOKEMOM sink caddy for a little while now, and it’s a solid upgrade for keeping the sink area neat and organized. The biggest advantage is the “stay-dry” design. Since it doesn’t rely on drainage holes, it works well on the countertop without making a mess underneath. It keeps sponges, brushes, and soap all in one place without water pooling everywhere. The stainless steel construction feels sturdy, and the rust-resistant coating is a nice touch for something that’s constantly around water. It also has a clean, modern look that fits well in the kitchen without looking bulky. Size-wise, it holds a good amount without taking up too much space, which is perfect if you don’t want clutter around the sink. The only thing to note is that since there’s no drainage system, you’ll want to occasionally wipe underneath or keep items from being overly wet so water doesn’t build up over time. Overall, it’s a simple, functional organizer that keeps things tidy and looks good doing it. Pros: clean design, sturdy, keeps area organized, no dripping mess Cons: no drainage (needs occasional wipe), best for moderate use
