100+PCS Technic Gears and Axles Compatible with Technic-Sets,Gears-Rack (Gears-Pins-Axles Differential New) for Car Building Brick Accessories Pieces Sets (Random Color)

My nephew loves STEM and uses these all the time. He makes awesome things with them and I love seeing his creativity.

lots of parts for the Grandkids to work with.

My little man asked me for some Lego gears, these are working nicely with his current collection. Price is good for the quality of the plastic pieces received, I would buy them again.

My budding engineer child requested cogs and wheels etc etc. Lego didn't sell them separately ...came across this and hey presto./. They fit, they work, they cause just as much pain when you tread on them. Happy with them, actually pretty good.

Got this for my son. My son liked it

I’m trying to make clock it works but I don’t have parts so got this This is right thing i needed

The pieces are fully compatible with LEGO and the quality is solid. It’s a nice pack to start with, but keep in mind that it doesn’t include enough pieces to build something substantial on its own—you’ll definitely need more sets to create bigger projects. Overall, good for beginners, but limited if you want to go further.

Muy buenos
