I understand it’s hard to start a new kind of material.
But as we have contacted your side before, the spool supplier who provide inner clip spool to BSSS quite business.
That means BSSS can only buy spools from other suppliers, and other suppliers only product the outer kind of spools.
For some reason of our other customers who couldn’t return inner clip spool to BSSS timely, our recycle system broke .
So BSSS have to buy more spools to sustain our production.
Hope for your understanding.
And any questions contact me freely.
