FabriTech Strip is the most iconic feature in every Bianca panty.
Fabric material is added consecutively in layers to form strips with Bianca logo "unprinted" - the basic of 3D printing technique, hence the name 3D FabriTech.
The strip enforces the waist and leg opening edges against curling, while maintaining shape, and elasticity.
The strip also exerts firm gentle grip, holding the panty in position, for secure and less wedgies worries.
