These lids work perfectly on Rocky Mountain tumblers. They are very well made and will last a long time. The price is perfect also. I got 4 for the price of 2 "other" brands!! I purchased the lids with the sliding mouth piece.
The replacement lids are nicer than my original lids. They are leak proof so far and they fit perfectly. Shipping was quick. Very happy customer!
This tumbler keeps liquid HOT for HOURS! Was happy to be able to get a replacement lid.
Needed a new lid, knew I was going to order a couple more 30oz tumblers, so I ordered extra lids, quick service, product is perfect, good to go
Fit perfectly on my older 20 Oz mug. Nice tight seal and good quality. Fast shipping. Had the lid in 2 days!
