AMMO by MIG Accessories - Tapes for Modelling
Item: Masking Tape 2 (6mm x 25m)

From the Manufacturer:

Perfect for airbrushing, as it prevents the paint from filtering, allowing us to draw the shapes we need. It leaves no trace and it is extremely careful with the surfaces where it is used, avoiding damaging base paint.

Thanks to its strength, it can also be used to secure joints while glue acts or as a guideline when engraving details on the plastic. It can be easily cut with scissors or even directly with a sharp blade on the model.
