I like Grooming Dept products a lot — high-quality and also interesting — but they do tend to sell out quickly. He has a bunch of new things that will become available on Friday, January 20, at 11:00am PST. (I put a popup reminder in my calendar so I can order before things are sold out.
Scroll down here to see what will be available. The Aion Hydrating Gel and Nourishing Balm are available now, as is Grooming Dept Rejuvenating Serum (which also serves as a nice aftershave balm).
