As each mold is handcrafted, it typically takes 20-30 days to produce. Due to the recent surge in demand, we are working diligently to fulfill all orders. Consequently, there may be a delay in delivery. We kindly ask for your understanding and patience during this time. Thank you! ⚠️ Important Tip:When pouring resin into the mold, the sides may bulge outward due to the weight of the resin. Please use a suitable support or place something firmly against the sides to prevent the mold from expanding and help maintain the shape of the finished piece.
