Hi Nicolas,
the bag will be biodegradable "foil" with a press zip closure and valve

Colour will most likely be silver as a base.

Hello, are you going to print the artwork onto the entire silver bag or having a sticker on top of the bag?

The printing will be the whole bag, not a sticker.

Good Evening,

Is acceptable to remove the white backgrounds from all three logos to allow the colours to come through? or are the images provided to remain with the white backgrounds as well?

Please note I have not received a response regarding my latest inquiry however I have submitted a design attempting to follow your instructions as closely as possible.

Sorry for the lag, I didnt see the notification email that there was a message.

Yes, removing the white background is fine if it suits your design better.

Thank you for the response. I have removed the white from the golden bean as well, but did not use this in this design. I can substitute it when required, I erred on the side of caution for the moment.

Thank you again.
Have a spectacular day.
Pat
