How to fit a SN*F
A SN*F screws straight onto the bottle neck. No tools: once you have the right size, it takes a few seconds.

Check your size
Every bottle has one of three necks: X-Small (DIN 18), Small (DIN 20) or Large (DIN 22). Pick your brand and product in the size finder, or look at the bottle list there. If you have bottles in more than one size, the 3-in-1 Kit holds all three.

Take the original cap off
Keep the bottle upright on a flat surface and unscrew the cap it came with.

Screw the SN*F on
Turn it until it sits flat on the neck. Snug is enough, don't force it. It uses the same thread as the original cap, so there is nothing else to fit.

Wrong size?
If it spins without catching or stops halfway, it's the wrong neck. Go back to step 1.
Fitting the push-button
The push-button goes on the same way, in the same three sizes. Once it is screwed on, it stays closed: press the button to open it, release it and it closes again.
