This is a nice standard replacement glass slide bowl made by GRAV Labs. It is all clear for a nice clean look and is adorned with the grav logo. This bowl slide comes in either 14mm or 18mm joint sizes.
Very nice glass bowl. The hole is a good size. One tiny "plug nug" and you're good to go. It's quality and well made. My only criticism is t+at its a bit large for one person if you pack it full. I pack it about 1/3 full for myself.
