The Ketunpesä ("fox's den") is Polte Glass's best-known piece, familiar to many enthusiasts by name alone. It is a hand-blown borosilicate glass bowl into which a reed stem fits just as it is.

The reed is a wear part and is replaced as needed, while the glass part stays. The solution is both old and practical: the natural stem lengthens the path and the glass stays cleanable, so the whole piece lasts for years in use.

This is the clear version, with no pigment hiding the shape of the glass. Each piece is made by a single glass artist in Tampere, so shape and weight vary between pieces, and no two are exactly alike.
