i have started to learn pen spinning recently and i saw all the pen those spinner use was unique so i decided to check how they modify the pen, eventually almost all tutorial material needed was either a namae pen or comssa(dong-a), but i cant find them in Singapore. Can some one tell me is there anyway i can make a easy mod(pen that i come find in singapore and where), or where do i find dong-a. I cannot buy them online because i am only 15 and my parent doesnt allow me to use their credit card
