Slightly on the expensive side for just connectors but they are considerably easier to use than the rigid connectors if you're not sure where you're going in the assembly phase of your wall panels. Allows your layouts to stretch out and breathe a little.
If they came in larger numbers at a preferential cost I'd probably use just these.

These are relatively pricey but will open up cool design options for your displays once you've exhausted your regular tricks.
A good additional tool for the seasoned ones who've been many times round the Nanoleaf block.

Of course Nanoleafs are already great in providing examples of shapes to create great designs, but flex linkers are definitely the way to release it a bit more by adding multiwalls possibilities for example. make sure you get yours.
see my lizard design ;)

When using at a high brightness I get audible buzzing noise suggesting a fault with them. Considering I paid £200+ I’m very disappointed and support has been no help. Wish I could get my money back!
