Refine 16oz Tumbler Wraps

I already have three full-colour PNG wrap designs ready for UV DTF printing. Each file is sitting on a solid white background and is not yet scaled to the standard skinny 16 oz tumbler template.

Your task is straightforward:
• Remove the white background cleanly (the artwork itself is fairly simple, no tiny cuts or complex edges).
• Resize each design to the usual 16 oz wrap footprint—roughly 9.4" × 5.5" at 300 dpi—or whichever precise width-by-height you normally use for a skinny 16 oz tumbler so the print company can drop it straight into production without additional tweaks.
• Return the finished files as transparent-background PNGs; an extra SVG export is welcome if you work in vector.

Please preserve all colours, keep proportions intact, and add a light bleed only if you feel it improves print reliability. I’ll review each file on receipt and sign off once they align perfectly to the template and preview correctly on a mock-up tumbler.
