ID request: 6mm S-Shape 3535 LED strip

A friend received a custom LED-neon sign as a gift. He plugged it into the wrong power supply and damaged the lights. I was hoping to source an exact replacement for these strips:

His crappy calipers suggested the diodes are 3535s on a 6mm strip with a cut point every 2 diodes / every 2.5 cm.

I have found lots of options for 6mm strips of SK6812, but they all seem to have cut points every 3 diodes instead of every 2.

Anybody recognize these exact strips and know where to source more?
