📮 How to use:

Fully package your item exactly as it will be posted.

Pass it gently through the appropriate opening without forcing or compressing it.
Check the remaining dimensions and weigh the completed package.
Select the appropriate Royal Mail postage service.

Using slimmer packaging may help keep suitable items within the Large Letter category rather than moving into the Small Parcel category, potentially reducing postage costs.

♻️ Materials:

Made using quality PLA plastic with raised contrasting lettering.

As each guide is individually 3D printed, very small layer lines or minor surface variations may be visible.
These are a normal part of the 3D-printing process and make every item slightly unique.

🧽 Care

Wipe clean using a soft damp cloth.
Keep away from high temperatures, prolonged direct sunlight and very hot vehicles.
