Nice drawer organizers with a lot of versatility.
Color: Clear
I bought these to organize my desk drawer because it seems like I can never find anything I'm looking for without taking everything out first,which is always a pain,so I thought why not try a set of drawer organizers.Talk about night and day,these things keep all my stuff tidy and easy to find now,it's great! The plastic doesn't feel cheap either and the different sizes are very versatile,they also come with enough rubber feet for all the containers,though you do have to peel and stick them on yourself,but it's easy and the adhesive feels very strong. I would definitely recommend these if you're looking for some great containers to get things more organized.

Easy to configure. So helpful!
Color: Clear, Color: Clear
My house has old bathroom cabinets that are too narrow for most organizers I have found. These organizers come in different sizes so I can mix and match the pieces to fit the drawers and items I have to store. I have filled two drawers with these and still have more containers to use. These are truly the tool for the job. They are sturdy, stable and I thought I would have trouble with them moving around but they stay in place while maintaining their versatility. If I need to switch out stuff, I just reconfigure the drawer. No assembly required. One of my most favorite simple purchases. I can’t believe I have lived without these simple but helpful organizers!

Great for lip gloss. Headbands. Little toys and trinkets for preteen
Color: Lilac
This set is great! I love the colors, and my daughter is obsessed with anything purple — light purple, dark purple, all of it 💜. She uses these for all her little trinkets like keychains, Q-tips, headbands, braces, hand sanitizers, little toys, and lip glosses. They’re easy to use, easy to clean, and great quality. She’s had them for a few months now and they’ve held up really well Different sizes. They like up for accessibility

Not sturdy, practical, or worth the price.
Style: TREE
Very cheap, unsteady. Thin material, feels like it will snap with very little pressure. Does not stand up well, so when I place jewelry on it (2 very small pendants on thin solver chains), it tips over, making it not very functional or practical. It also is short, so even short chains fall onto the table (no tray below). I could have gotten a better one at Five Below for less. Really disappointed.
