Who sells Nestwell

Greetings, I've been searching for some good bed linens recently. I came across these soft fine fabric sheet sets from Nest Well, specifically their well-known fitted sheet collection. I'm trying to figure out where to get these Nest Well bed sheets in king or queen size these days.
 
In addition, can anyone tell me where to find these Nest Well bed sheets or if Nest Well is operating? I really liked their True-Grip fitted sheets design where the sheet stays firmly in place all night. If anyone knows who sells a sheet set with a True-Grip fitted sheet, please let me know!
