I hoard the one from Ecotools. They were selling them at Ulta for $2 and anytime I was near an Ulta while traveling I would buy the stock out. They took them off Ulta.com and in stores. But I think they still make them. Otherwise the real techniques one has a cover. And I saw a version the looks like RT at Tjmaxx from a company called precision beauty by swissco. Also great brushes.
