How old are they? In the video, they look like they are about 3 weeks old (which is way, way too young to be sold, btw). They don't look like Dwarfs to me, I believe they will get much bigger. There are definitely harlequin markings on two of them, but there is also one that appears to have no markings at all (something that should not happen in a purebred Harlie litter). I've seen a lot of harlequin markings in Mini Rex and Holland Lops, but they generally brindle more; areas of black that large with so little brindling makes me think that the markings came from a Harlequin rabbit (the breed). My guess is mixed large-ish breeds, with Harlequin being one breed in the mix.
