ETopLike 1000PCS Stainless Steel Screw & Nut Set Assortment Kit Repair Tool with Mini 3 in 1 Screwdriver Keychain for Glasses/ Cellphone/ Watches

Perfect sizes for a variety of glasses/sunglasses.

I got this set for a 3D printing project I recently completed. I designed and 3D printed a carrying case for a rosary, and used some miniature hinges and hasps I have on hand. Said hinges and hasps came with wood screws that are way too hardened; Every time I'd try to attach a hinge or hasp component to a case half, the screw would break off flush, and I'd have to 3D print another case half. So I got this kit. I revised my case halves to have small hex pockets for the nuts I chose to use, and printed the revised halves. This was an inadvertently wise decision on my part; The only tool I could find that would fit the nuts is the tool that's included with this kit! I see now why other reviewers warn against losing that tool! At any rate, this set up helped. With these fasteners I was able to securely fasten hinges and hasps to my case halves and complete the project, and nothing broke during assembly. I only have one gripe about this kit, and that's the case it comes in. Sometimes the rotary lid snags a little as I rotate it, and I worry it will break. If it does, there will be no way to keep the container closed. I'm not using any more of these fasteners at this time, but if I ever do, I may design and 3D print a container of my own to store these fasteners in.

They arrived in a round cassette. Two of the compartments were open, spilling out all their contents into a plastic bag with unsealed corners. Most of the nuts were lost. I really need them, but hesitate to buy again!

Has all the sizes expected, only negative is with shipping the nuts and bolts moved around (they are really small) and ended up getting mixed up. Would love it if the packaging was improved so that pieces stayed where they should during shipping.

What can I say. They are tont screws. The price was worth it.
