I received this as a gift, but I never used it and have kept it in storage. It's a 18-8 stainless steel mug bottle. It's the type that you open by twisting the lid. When you twist the bottom lid, it makes a squeaking sound, but it was like that from the beginning. The form is beautiful, and the simple and stylish design in brown metallic? and dark brown is suitable for both men and women. Since it's been stored at home, there may be some minor scratches, but overall it's clean. Please check the images carefully. Please refrain from purchasing if you are concerned about minor details or are overly sensitive. Since there is no box, I will wrap it in bubble wrap and ship it via Letter Pack. For those who understand everything, thank you. Total length approximately 18.5cm Top lid diameter a little over 8cm Bottom diameter just under 6cm
