I'm very late to this thread, but according to a review for these replacement paddle brushes they work great with ILNP. Haven't bought them myself yet, so I can't say myself if that's true or not.

can confirm these fit ILNP bottles! much more affordable than the ones ILNP offers. Doesnt come with caps, but the brush is easy to remover with a good grip or some pliers. https://a.co/d/00N4qAxa
