Meet the Willy Glass Guy Koffing Proxy Core Tip — a character-driven glass sculpture handcrafted in the USA by Willy Glass Guy, an American heady glass artist celebrated for bold borosilicate character work. This piece channels the iconic poison-cloud energy of Koffing into a fully functional Puffco Proxy Core tip — equal parts collectible art and smooth-hitting concentrate accessory. Each piece is individually lampworked, so no two are exactly alike.
