Because the quality of shellac flakes is affected by moisture, and we cannot control the care with which it is handled and stored after it has reached the customer, we limit our guarantee to 50 days - 7 weeks from the date of shipping.
Shellac Shack recommends that you keep the zip-lock bag sealed and that you store the flakes in a low humidity area. Some folks like to keep their flakes in the refridgerator where the humidity is low. This will also keep the flakes from blocking ( sticking together ) on hot summer days, although blocking will not damage the quality of shellac flakes. It's good to remember that on warm humid day there is much more water in the air ( per volume ) than on a cool rainy day.
If you have any questions, please give us a call.
