The design of the toy is fantastic for the user. It is well designed. The dimensions are close to what is stated. There were small deviations, but small enough that it is expected with glass items. The plug has a nice ergonomic feel to it in your hand. The fact that it has a nice gentle slope from the widest point to its smallest point is amazing. Also, the shape of the head is great when inserting it. The color of the plug and glass make it quite gorgeous as well. The glass will cause distortions that are lovely when you look through it. The distortions become more beautiful with the pink hues of the plug. When inserting it, I did experience some pain. For more experienced individuals, the size is nice, but newer individuals may find it is a tad large. Overall, the plug is designed for comfort and enjoyable experience for all users.
