A compact 10 oz car tumbler with a straight, cylindrical lowboy silhouette: the coated body sits between a polished stainless-steel rim band at the mouth and a matching steel base band, and the interior wall is stainless steel. Construction is double-wall vacuum insulated 18/8 (SUS 304) stainless steel inside and out, the listing artwork claims drinks stay cold up to 24 hours and hot up to 12 hours, and calls out BPA-free, non-toxic, food-grade material. The cup closes with a low-profile clear plastic slide-lock lid that leaves a direct-drink opening, there is no handle and no straw, keeping the profile suited to vehicle cup holders and desk use. Fifteen matte stock colors are charted, from neutrals (black, white, bare brushed steel) to brights (mint, orange, yellow, rose pink, red, purple). For branded orders the factory documents silk-screen and laser engraving plus a wide finish menu (powder coating, gradient powder coating, spray, rubber, rainbow, rose-gold metallic, water transfer, 3D and heat transfer printing, electroplating), retail packing choices (color/white box, egg crate, cylinder, display box) and a full eight-step OEM/ODM workflow from requirements to shipping.
