@Sniper12: The classified ad was removed, so I couldn't see it. I have a collection of 20oz and 30oz Ozark Trails tumblers from Walmart (less than $10ea). I've tried about 4-5 different brands of handles for the 30oz and they all fit, but most don't fit very well. I found that the ones that fit the best are the Overlord Grip Handles.https://www.amazon.com/Overlord-Grip-Handle-30-Ounce-Tumbler/dp/B01GOWOGZC/ref=sr_1_1?ie=UTF8&qid=1481079782&sr=8-1&keywords=overlord+grip+handle+for+30-ounce+tumbler2 handles for $5.30 with free shipping. 4951
