Worked great for my project!
I bought these to make my own storage rack for a motorcycle tour pack and they worked exactly how I wanted them to.

Niubid 10 Pack 1/2 Inches x 12 Inches Black Malleable Steel Nipples Fitting, DIY Steampunk
These pipe nipples arrived cut to the listed length and matched standard 1/2″ threading. Threads were clean and consistent on all pieces, and they threaded smoothly into matching fittings without cross-threading. The black finish is even and gives a classic industrial look that works well for steampunk-style builds, shelving, or exposed pipe projects. The steel feels solid with good weight, and the pipes stayed straight once installed and tightened. Used for DIY decorative and utility builds, and they performed as expected with no visible defects or damaged threads in the pack.

Using them to make a gunstock for VR games
These are the pipes used to make the Sanlaki 3d printed gunstock for VR gaming, and they are great quality for that purpose. I had to knock off a star though because mine arrived a little rusty and that rust transfered to my hands and onto the 3d parts of the printed gunstock as I was assembling it, which is kind of disappointing. Since I 3d print though I have lacquer and can just coat the pipes, but it feels like I shouldn't have to do that with a brand new product. Other than that though, I am very happy with their quality and they will server their purpose very well.

Craft use only
Do not use this for actual plumbing. Not plumbing quality piping. It’s good for light weight crafting. Not heavy shelving or plumbing work.

Right parts and on time
Everything came as expected. Pipes were already cleaned and painted. Most come oily. Quality parts.

Try to get all your same size nipples at the same time.
This pipe is not as dense/heavy as gas pipe I use for hvac. The tees are also shorter. I'm not sure how they'd fair in that application. However, I used this pipe to build a clothing rack with shelves and it's sturdy enough to hold over 150lbs without any issues. If your intentions are for something of this nature, its fairly priced and a quality product. I was short some nipples and bought a 2nd batch. Slight variation in the lengths in doing that. Otherwise, no issues. I used 1/2 only for my project.

Si quieres un producto demasiado vintage, sies para ti, pero definitivamente lo devolveré porque los tubos llegaron super oxidados. He comprado con otros vendedores productos con mayor calidad y mejor precio. Adicionalmente, solo están empacados en un sobre.

llego muy oxidado, hice al mismo tiempo un segundo pedido y hasta fecha no ha llegado, me enviaron un comentario para devolver el $, falta calidad en la pintura de acabado, por el precio debería tener mejor calidad.

Was planning to use this for DIY. Was waiting for this with full of excitement. When it arrived, I immediately opened it up just to feel fully disappointed. Everything was covered in rust. Definitely wouldn’t recommend this item

These pipes are thin, and the paint works really badly, with marks and scratches.
