Collaboration item between Shin Arata-san's production, ELNEST CREATIVE ACTIVITY, and RIVERS. A vacuum flask with a capacity of 500ml. Ultra-lightweight at 230 grams. The muted blue color is very beautiful, and it was a sold-out item. I purchased it a few years ago and used it for only one summer before storing it. There are no noticeable scratches, but there is a feeling of use, so please consider if you don't mind. - Brand: RIVERS x ELNEST - Model Name: VACUUM FLASK STEM - Capacity: 500ml - Accessories: Bottle leash - Instruction manual: Included Thank you for viewing.
