UNIQLO stainless steel tumbler. It has a black lid and excellent heat retention. - Brand: UNIQLO - Material: Stainless steel - Lid color: Black - Bottom color: Black Thank you for viewing. I used it once and it has been sitting in the cupboard for a long time. There is no box or instruction manual. I will wrap it in bubble wrap and put it in an envelope to send it by non-standard mail.
