From left to right: Memento dye ink reinker; Versamark reinker; Stampin Up reinker; Gina K. Reinker; Ranger Stickles; Ranger alcohol ink; Ranger distress oxide; Avery Elle pigment ink reinker. I knew the Avery Elle would be too tall for this case (they're 20 ml, just over .5 oz), but I thought folks might also want to know that the Avery Elle bottles are also to big around to fit in the slots.
Bottles that measure 1 inch diameter and then about 1-11/16th inches (from bottle “shoulder” to the bottom of the bottle) should fit.
Update Nov. 2020: the new Stazon pigment ink reinkers don't fit. They're too large in circumference.
