Orders & Delivery

Please note that the purchaser is responsible for inputting the correct shipping address. If an incorrect or incomplete address is entered, SINLASH cannot be responsible for replacing the product. 


 The purchaser is also responsible for making sure that the shipping address entered is a secure address.  We cannot cover the cost of lost or stolen packages, nor can we interact with the shipping company to locate your lost package, if the tracking information says it was delivered or is en route to the shipping address.  If the shipping company shows the package as having been delivered, then we will assume that it was delivered and that something must have happened to the package at its destination. 



Standard orders are dispatched via Royal Mail 24 or 48™ delivery which usually takes between 2-5 working days; however this may take longer subject to demand i.e. the Festive Season is an exceptionally busy period for Royal Mail, and greater demand is expected on their delivery service across the UK and Internationally. For lash apparel we use a third party company so the shipping can take a bit longer around 5-12 days, tracking well be provided.
