Diamond bottlenecks are hand-made in the UK, in the heart of the traditional glass-working part of the Black Country. Cut from real wine bottles, they are de-seamed and polished to a super-smooth finish.

Soda-lime glass is a much more superior product to the clear borosilicate glass used in most commercially produced slides. The density, hardness and smoothness gives a great tone, singing sustain and unparalleled playablity.

Please note these are handmade from real wine bottles, so there may be some slight variations in size and colours. Typical sizes are:

Internal diameter 19mm tapering out to 21mm

Length 55mm

If you want a slightly smaller or larger size, please let us know and we will do our best to select one from our stock to meet your requirements.
