I haven't used this since purchasing it elsewhere. I took it out of the box to take photos for the sale. Although there was no coupon, it was listed as new. The size was quite different from what I had in mind, so I'm selling it. From the perspective of a regular user, there's nothing particularly concerning, but I'm not sure how it would be perceived from the perspective of a collector. Please make your purchase at your own discretion. - Brand: Stanley + Starbucks - Model Name: 3-Way Stainless Steel Tumbler - Capacity: 887ml - Color: Mint Green Gradient (Blue to Green) Instant purchase OK Thank you for looking.
