Extreme cold or heat can affect our products: some of our liquid-based products may freeze and expand due to temperatures below 0°C, and some solid-based products can start to melt in high humidity. In extreme weather situations, we can provide a next-day shipping service for these products, at an additional charge. This will ensure that your products do not sit in storage overnight, potentially causing leaks and damage to the rest of your order. Please contact us to inquire about specific products.
