Brosky Pattern Stalowa butelka na wodę w kolorze morskim 680ml

Brosky bottles are made of double-wall stainless steel, providing effective thermal insulation. The interior of each bottle is coated with a ceramic lining, helping beverages retain their natural taste and aroma without any metallic aftertaste. The double-wall construction maintains drink temperature for many hours while protecting hands from heat or cold. Brosky bottles are durable, leak-proof, and resistant to damage, while their lids are equipped with a straw, air vent, and a convenient carrying handle.
