These screw caps are a premium plastic version of the metal screwtops commonly used on commercially produced wine.
You can use them on wine bottles you have purchased with metal screwcaps. Remove the "skirt" part with carefully with a stanley knife or sharp utility knife.
These can be applied by hand and look very smart - great if you are wanting to take your winemaking to the "next level".
Whilst they are intended for single use commercial production they can be succesfully reused as the thread doesn't get damaged in the same way that the metal screwcaps do.
Black only available.
For quantities of 250-1000 there will be a delay of 2-3 days before despatch. They will also be measured by weight so there may be a slight +/- variation in quantity.
