Review: Perfect fit and functionality - I have a number of Akro-Mils 30164 storage bins for organizing the electrical supplies at our shop. I needed a way to securely separate the items in each bin, so I thought that I'd try out the separators supplied by the same company. These separators are so much better than ones I've purchased for other organizing projects. They are super strong, without any worry about breakage, and they fit really well with a dovetail style joint into the slots in my Akro-Mils storage bins. They fit so well that I had to use a tool to lever them out when I'd placed a few of them in error. Their design is such that once installed, they actually keep the sides of the storage bins where they are supposed to be instead of bulging out. Awesome value for your money.
Review: Great for manufacturing 5s projects and quality sorting - The size is perfect for the bins we needed. Color is perfect, bin is sturdy, easy to use and easy to clean. Great value for the price.

### ⭐⭐⭐⭐⭐ Works as intended and expected of container dividers.
