I have been seeing and reading a lot about jade beauty rollers so I wanted to try one for the puffiness around my eyes from not sleeping well. I had read to put it in the freezer for about an hour before using it. The jade stones already have a natural cooling effect but the extra coldness really helps with my under eye area. The tool has a longer roller for the larger facial areas and a shorter roller for the under eye areas. The longer side is 1.9 inches wide and the shorter side is 1 wide. The roller is 5.9 inches long so it doesn't take up a lot of room in my makeup bag. The roller comes packed in a nice lined box so I can be given as the perfect gift to any beauty tool lover. The roller has a smooth gliding action and the stones are very pretty.
