It’s empty in here!
I bought some of these for a road trip with three large dogs, as their china bowls wouldn't have withstood the battering of the roof box every night and a different hotel room/farm/country every day! They all stacked inside each other, and the 4.5 litre was a perfect size for water in a Tuscan heatwave. Pretty lightweight (exactly what I wanted), but very robust nonetheless, and fantastic value for money.Still nice and shiny with no dents in despite their ordeal. Would buy again.
