I believe I purchased the white one at a pottery fair somewhere. It has a groove on the lower side of the exterior, making it easy to hold. There are crackles and some stains inside. Please check the last image. I will try bleaching it, but I apologize if they don't come out. It feels substantial and looks a bit expensive? The brown one is light and easy to hold. I have a memory of receiving this one as a gift, but I'm not entirely sure. The glaze flow inside is beautiful, and it doesn't look used. I have been storing them in the back of the cupboard. They can be sold separately. Please feel free to inquire. For those who understand the condition. Would you like them?
