Refill packs are a lighter and better way to refill your 6 oz Salis Salt Scrub! It is more economic and cheaper then shipping glass. However, refill packs should immediately be placed in the original 6 oz glass jar that was purchased. The salt scrub and essential oils do not work well with the plastic. For this reason, please immediately place contents inside the original glass jar. At this time we are unable to sell the contents of the refill pack to users who have not previously purchased a 6 oz jar. We strongly encourage you to purchase the 6 oz jar before purchasing the refill pack. Thank you for your cooperation. Enjoy the refill and saving the environment!
