The Noble collection is the main official producer of Harry Potter wands (other licensed companies do exist, but Noble is the most popular). Excluding sets, and variants of the same wands (they have different listings for the same wand if it comes in a different wand box or if it illuminates), there are currently 60 different wands available to buy individually (as of February 2022). That doesn't include Hagrid's Umbrella which technically contains parts of his wand.
