CenturionPro Electropolished Dual-Purpose Hybrid TumblerIn 2020, we moved away from offering separate wet and dry tumblers and now offer a Dual Purpose Hybrid tumbler instead. The Dual Purpose Hybrid tumbler has been extensively tested and found to trim wet product better than our old 1 8 Wet Tumbler and dry product better than our old 1 4 Dry Tumbler. This 1 4 (metal slats) Electropolish Tumbler is the Old 1 4 Dry Tumbler. We recommend that customers purchase our new Dual Purpose Hybrid tumbler instead,
