found a stopgap until i can get an order in with slowtech... an old 0mg strawberry bought at vapefest either 2, 3 or 4 years ago fits and works... though a little hard on the fingers being a clear plastic P.E.T. bottle... or a bottle from my wraith will also fit i think. However gonna have a look at modmaker as i suspect delivery will be faster, THANKS for the tip.
Either way I'm buying 10 bottles!! thought I had a couple of years ago but must of just looked at them and never gotten around to checking out.
