At DR.WU, we use an Airless Pump System. With this revolutionary packaging there is no dip tube (straw), but rather a disk that rises to evacuate the product. This makes our packaging produce less waste. The airless pump delivery will ensure 99.9% of the product is pumped out as the disk moves up the bottle. No more opening up the bottle and scraping it out!
When product won't come out the bottle, DO NOT open the bottle. Simply by putting the top back on and tap the bottom of the bottle on the back of your palm a few times (5-10), then try pumping a few times slowly. Repeat the tap and pump process for several times.
