Shimotsuke Ayu Vacuum Cooler 14L Thermos There are dents on the bottom (several places, though not very noticeable). I think I mistakenly used the lid from a 6L cooler (I also own one), as the magic marker doesn't fit completely. It shouldn't affect use, but please refrain from purchasing if you are concerned. - Brand: Shimotsuke - Color: Red - Material: With metal lid Thank you for looking.
