I have to apologize for not having mentioned explicitly at the beginning that the new bottles would be an addition / alternative to the current design, sorry.
So to make it very clear - if you order the Bulldog paints now, you will receive them in the "old" bottles (btw. I love the vintage look, too). If the new design goes into distribution in the future, there will be the possibility to choose the jar design during ordering.
We had had a discussion similar to the one here with czech WWI fans before I placed this poll. Not surprisingly the outcome was basically the same.

I was one of the supporters of the new design, as it fits my needs better than the current jars. For my 1/144 scale, I need to lighten up the paint by approximately 25 %. Therefore it is a big advantage to have additional free space in the jar to add white or yellow. Nevertheless, it has been clear since the very beginning that the new design would not be suitable for everyone.
Once again many thanks for your feedback and inputs, I will keep you updated on further development!
Here the answers to further points which appeared in the discussion:
@Rick and Lance: some good news, dear friends, Sergey is currently negotiating with one local distributor in the US who would like to sell the DB paints. The current obstacle is the shipping to US, but we are looking for a suitable solution.
@Borsos: at this point of time the DB paints are not available from stationary stores, only via webshop. But if you are interested in purchasing some paints, let me know and I will try to find a way to hand them over to you next time you are in Prague.

Cheers
Ondra
