● Ongoing R&D

2021. 8. 23.

1. 18K eureka gold nib developing (replaces previous AuAg, 14K nibs)

2. silver & gold powder fabrication 

3. new end designs; 8 kinds

   -eclipse type: sausage, cone, flat, flat arc

   -rod type: sausage, cone, flat, flat arc

4. eureka hybrid model (hybrid of symmetry and asymmetry ; replaces asymmetry)

5. eureka nacre(mother-of-pearl)-urushi technique
