Questions
Does it work for 5 L bottles with a handle?
The handle is usually fitted to the neck as a separate part after blowing. Tell us the handle and cap model and we will confirm compatibility.
Which caps fit?
Caps for 38 mm bottle necks. Send a photo of your cap or its standard so we can check compatibility.
Can it be blown into a smaller bottle?
The 64 g preform is designed for a 5 L bottle. Other sizes need a different preform and mould: tell us what you plan.
Not sure about the standard?
Send a photo of the neck next to a ruler and we will tell you which preform fits.
