Looking for a mini pocket thermos that combines premium materials with true portability? The KS-248020 200ml pocket cup is an ultra-compact, lightweight vacuum insulated flask built for B2B buyers, promotional gift companies, and private-label drinkware brands. Weighing only 140g and measuring just 5.7 × 13.5 cm, this slim small capacity stainless steel bottle slips easily into handbags, backpack pockets, and laptop bags—perfect for commuters, travelers, and daily hydration on the go.

What sets this OEM pocket tumbler apart is its upgraded material structure: a 316 stainless steel bottom paired with a 304 stainless steel inner liner and 304 stainless steel outer shell, delivering superior corrosion resistance, durability, and food-safe performance. The double-wall vacuum insulation keeps drinks hot or cold for hours, while the minimalist matte finish creates a clean surface ideal for custom logo engraving or printing.
