Polte Glass from Finland has made these awesome CFL (colour changing) slurper sets

Handcrafted in Finland, Polte Glass brings together precision, creativity, and a deep respect for the art of glassmaking. Each piece is individually shaped by a single artist from start to finish, transforming durable borosilicate glass into functional works of art. No mass production, no identical pieces, just skill, patience, and craftsmanship in every detail. 

From vibrant colors and layered designs to organic forms that come alive in the light, Polte Glass creates pieces that are as beautiful to look at as they are enjoyable to use. Their work perfectly balances utility and artistic expression, showcasing the passion and dedication that define Finnish glass art.
