This is a classic straw building set by Ggiibro brand – with thin, flexible plastic tubes and hard connectors. The tubes bend easily, but they can’t hold any shape on their own. Once you release them, they will immediately return to their normal, straight form. They also are just smooth hollow plastic straws without any details to attach to each other.
So, you will need special connectors to connect and hold the straws together. Main connectors have small pins that go inside the straws’ hollow ends and then hold them in place. These things can connect straws in different positions, but they obviously attach only to the edges. Because of this, many modern straw building sets also have connectors that can wrap around a plastic tube and hold it in place. These connectors greatly increase the number of building options the set has. This set has connectors that can do both of these connection types.
The straw sets are very different from building blocks. Instead of the solid, sturdy constructions, they produce a bunch of lines forming a 3D shape. These crafts are lightweight, flexible, and a bit abstract. Not all sets have extra pieces like wheels, but you will be able to lightly bend and twist the craft you made.
