About ONE PLUS ONE

Founded in 2020 during the global pandemic, ONE PLUS ONE is dedicated to providing innovative and eco-friendly adhesive solutions for leather artisans and DIY enthusiasts. Our products are proudly made in Taiwan and designed to make leather crafting easier, cleaner, and safer.

We specialize in non-toxic, ONE PLUS ONE Glue Pen, free from toluene and safe for long-term use. Our breakthrough design combines a marker-style applicator with liquid adhesive, allowing both beginners and professionals to apply glue precisely without mess. This user-friendly innovation has redefined how leatherworkers bond their materials with ease and accuracy.

In 2024, we introduced our latest advancement—the ONE PLUS ONE Viscous Adhesive. This new formula provides a smoother, more convenient application with exceptional tackiness, allowing immediate adhesion without long waiting times.
