They seem to time products to my needs entirely. The hair oils coincides with my holidays and spritz with long-flights. It's a fantastic opportunity to try brands that would not necessarily fit into my radar but that once tried I would certainly purchase again. There had not yet been one product that I have been disappointed with. The girls in my offices use other branded boxes and have been continuously disappointed with one or more products each month. When I receive my cohorts box it's almost an event to see what's inside.many of them have now moved to cohorted. Thank you!
