Why this 12×16" size?
12×16" is a versatile mid-range size ideal for hoodies, jeans, small gift boxes or 2–3 folded T-shirts. It’s large enough for fashion and boutique orders but still light for cost-effective shipping. The pink finish makes parcels stand out on doorsteps and social feeds.

Storage & performance
Keep flat at 13–21 °C. Let cold stock reach room temperature before use to ensure a consistent seal.
