Wash your hands before handling.
If necessary, cool the refill. Take your empty Kali déodorant tube *leaving the plastic tray at the top*.
Keep the bag on the top of the refill and insert the product.
Gently push the deodorant down.

OOOPS !
If, unfortunately, you threw the plastic tray in the trash with the rest of your old deodorant, and your refill is taken in the plastic tube, here’s the solution!
Insert a straw around the stem about 4 cm deep (it must be bigger, my stainless straws were not working, I took a plastic straw).
Gently pull on the straw, the deodorant should come out, otherwise put in the refrigerator for a few minutes and try again.
You can now buy a new empty tube from the online store, or from a retailer.
