MyBuild Bricks Creative Building Blocks Pack F502 - Build Mech Shoulder Section or Foot Plate Ball Joint 18 Pieces, Age 12+

My grandson lives Legos and he loves these extras.

I can safely say I love this product. I got the base kits previously and saw how I needed more of these joint sections. The sheer number of them is super nice. Even if you don't use them all at once, it's bigger to have a dozen or so spares.

The socket is a little tight when coupled to Lego balls, but they work. Good for forearms for small Lego mecha.

This is a really nice idea but here is a huge issue they dont really have a good grip when using official lego clips instead they fit very loosely and so it will only really work with other products in this line. Disappointed

My son needed one of these pieces to replace one that broke. When he saw there were 20 in the package, he was thrilled at the building opportunities. The amount of smiles and creativity per dollar makes this item a real bargain!

My son who is Autistic loves Legos and all sorts of bricks. He asked for these specifically by name so he could make his creations so they can bend. He loves them!!!

Bricks snap together very tight and hold poses really well.

Best for building anything that needs articulating..All MyBuild products are top-notch and do not feel cheap like other non-lego products.
