As we mentioned before, the anti yellowing effect of white lace can only be maintained for 6 months at most when it is normal. This is the industry standard of lace, and there is no way to achieve a longer time. In addition, we also noticed that on the Yellow samples you sent back before, in addition to our lace, other shoulder straps and acorn roots also have the phenomenon of yellowing, which leads us to have no way to confirm that our lace anti yellowing effect is not good, because it looks like it is caused by improper storage, so please forgive us for our inability to accept this deduction<br>
