lab experiments

These are neither spring steel nor stainless steel. They are medium grade steel rods. The specs are not accurate, based on my sizing them with my calipers, which indicated some were above spec and some below spec. If you just need hobby grade steel rod, these may work for you. If you are expecting music wireor piano wire as was once widely available, this isnt it. Neither is it spring steel (once bent, it stays that way and will not spring back). It appears to not be stainless steel, based on the fact that you can pick it all up with a magnet, and some of it appears to have been shipped corroded. However, if you only need an assortment of small steel rod, (not quite as good of quality as the wire used to make a paper clip), this may work for you. It is a low grade product, but may be ok price wise if you find a few of the pieces usable. I did find once piece in all of this to suit my needs, and will probably find a few other pieces of this pack useful to have on hand. However, except for a few pieces, most of this (and almost all of the smaller sizes), are junk to me. If I knew of any option of getting a better quality, I would recommend it instead of this. Im not a fan of Chinese junk, but what else are we to do?

Great craft product, it can be bent using pliers. Shipped in a plastic tube so they arrive strait

I bought a watch that was missing a rotating bezel click spring and this allowed me to make a replacement. Outstanding value and will surely allow for many future fixes. Fantastic packaging as well.

I personally didnt know what size of spring I needed to make, just knew it needed less than 0.5mm and this bundle has a lot to choose from. I used the biggest size to help make a 3D printed Torsion spring maker. I really like the amount of rods you get giving anyone plenty of room to mess up a few while you get the hang of spring making. Came packaged nicely in a plastic tube , no bent rods. Will have to come up with some uses for the unused rods. Good to have on hand too I guess.

the wires are wrapped in cellophane tape, making it difficult to separate individual pieces without bending or kinking. especially true of the smallest ones. they were shipped in a nice tube so there was no reason to wrap them with tape the wires themselves are fine and as advertised

Its a bundle with crappy scotch tape around the whole mess, and around each gage - really hard to pull it off the hair-thin wires. No idea what each wire gage is - worst is they gave me a ton of the really thin wire and only a few of the thicker wires. Also the tube it comes in was covered in scotch tape on both ends. Hardly professional.

I wasnt sure what size I was going to use for a project. This was EXACTLY what I needed. You get more of the the smaller ones. So a single large one, two of the next, and so forth. I think maybe 30 of the super thin ones. Handy storage tube as well.

I used this wire, baking soda and super glue to repair a dental clasp. Saved myself nearly $200. The multiple sizes made it easy to select the exact size I needed for the project.
