They are very easy to fit. Simply press down onto the bottle until you hear a click, then tighten to seal. If you are re-using screw cap wine bottles first take of the security tag ring from the neck of the bottle. These caps won't work otherwise. The bottles need to have a 28mm o/d screw with at least 2 rows of pitch to the thread.  The cap incorporates a tamper-evident shroud which makes these Novatwist caps suitable for commercial bottling too.

At present we have 9 lovely colours, a Burgundy red, Pillarbox red, warm Ivory, green, a gorgeous bright blue, gold, Black, Silver and Sunshine Yellow.  There will be more colours later in the year. These caps come to us in boxes of 1000 so we can accommodate different quantities if you have any special requirements - please just message us. I have listed quantities of 12, 30, 100 and 200. Obviously the more you have the better the unit price.   There are some mixed pack options, if you select on of these don't forget to tell me what colours you would like. If you don't tell me l will send an assortment of all available colours.
