Bottega Copper Tumblers

I chose these tumblers for Bottega for their easy, hourglass shape (which fits perfectly in hand), and for the way they keep drinks cool longer. Hand hammering the copper gives it unique texture, improves its strength and beautifies the patina. What’s more, copper is naturally antimicrobial, which ensures very “clean” cups for life. Insides are stainless-steel. Hand wash. Imported.
