Generally once sold out we can't promise restock ( •́ ̯•̀ )
If you see sold out you can apply for restock notification at each design page!
(it doesn't promise we'll restock yet, once restocked you'll get email notification)
Generally restock takes more than 2weeks + or few months if we have new designs to launch.
(the restock will be decided based on how many customers asked for the restock notification. If less (1~3) most probably we won't restock. and some designs are we can't get the parts anymore so will not able to restock.)
