Magnetic Dellner Coupling Pack - 8 Couplings 

A little on the small size ,haven’t try yet don’t yet how they would work but I’ve kept an open mind

It’s best to start with the couplings look amazing! They also have incredible strength and hold together really well. That is unfortunately their slight downside. A couple of the magnets have pulled out. Though this was quickly rectified by using a lil glue and working out the magnet orientation! All ends well

Works great

Arrived well packed and they simply work very well.
