The white exterior and black inner layer ensure opacity; the durable material protects contents against tearing and moisture.

Insert the product, remove the protective liner, seal, and apply the label. Ideal for efficient e‑shop dispatch.
These white courier poly mailer envelopes speed up your packing thanks to the quick peel‑and‑seal closure.
