Flask & Travel Mug Cleaning Set 5 "very versatile!" Ms green 18 March 2019 This set is brilliant. The cleaning tools reach just about everywhere and not just for flasks and travel mugs. I am using mine to clean the parts of my dogs drinking fountain and for the first time ever it is sparkling. I am also using it to clean the pump as it gets right into the crevices. I have just started and I am sure that I will find a host of other hard to reach things that these will work on. Thank you Lakeland, you've done it again!
