The 68845NV basic student molecular model set can build triple bonded structures such as alkynes.
The image shows ethyne, propyne and the two isomers of butyne. Triple bonds are shown using the 50mm white flexible bonds. Single covalent carbon-carbon bonds are shown with 30mm grey bonds and carbon-hydrogen with 20mm. Build these & other alkynes with the Indigo® Instruments 3D Molecular Model Builder

Every Orbit molecular model set sold by Indigo Instruments is fully compatible with others you might own. You can replenish any set or customize it with Genuine Cochranes of Oxford Orbit Atoms.
I've had consistently great service from this company. Our students seem to really appreciate the reasonable price. In the years that we've used this product, not one has been returned due to defects.
Considering how many of these we sell to schools every year, that is high praise indeed. Thanks letting us know.
