Diameter of the rod tip they will fit is from 2.7mm to 3.2mm(other sizes may be available soon)
Length of actual glow stick 47mm x 4mm diameter
I use these all the time and they are great, we have actually had them last 48hrs, unlike the BCF ones which have died after 20 mins :evil:
Post here or pm if interested
Heres a pic of them
