This 20oz or 30oz stainless steel skinny (non tapered) tumbler is double-walled & vacuum insulated to keep your drinks cold/warm for hours! Each tumbler comes with a plastic Straw (or you can upgrade to a metal straw, depending on available stock) There is no actual glitter on my tumblers. This design process is called sublimation, a process of infusing specialized ink directly onto the tumbler for a full vibrant color design. No vinyl or epoxy involved, which is much safer for you & I. Please note: Some full-pattern tumblers MAY have a visible seam, its is normal & very common, it is not a defect. Color of design may differ slightly depending on your computer screen. If your tumbler is being personalized, all personalization will be done on the opposite side of the seam for best results. I will always message you with a mock up of the design for your approval before I make it. Animal & Flower Pencil Tumbler 20Oz Skinny | Non-Tapered/Personalize With Name Or Phrase/ Gift For Teachers
