Packaging mock-ups of mailer box, sachet and card mailer envelope

Information for the business: Supplement company
Industry: Healthcare
Design details: Looking for series of background and social media images to be created of mock-up shipping box, sachets and card mailer.

Already prepared design concepts on Inkscape however would be open to suggestions and edits.

Product will be shipping in tear open sachets with simple one-colour design, with letterbox sized shipping box and rigid card mailer also included.

Total outcome would be:
1x mailer box on desk or similar background
1x mailer box in blank/pastel background
1x sachet on (different) desk or similar background
1x mailer envelope box in blank/pastel background
1x mailer envelope (different) desk or similar background

Thanks!
