The Yves Durif Brush D'Or

What you are looking at is The Yves Durif Brush D'Or, a product. Between versions of the same thing, it is usually the details — capacity, finish, what is included — that separate them. Check the measurements and the contents against what you already own before choosing. Whether it is discounted this week says more about the shop's stock than about the product. Store it dry and out of direct sun, which is the simplest thing you can do for how long it lasts. The cheapest listing is not automatically the best deal: delivery and any code applied at checkout decide that.
