What you need to get the extra product out:
-container to put the product into
Cut the bottle at the "curves"
Look at all that product in there!
I just use the wand to scoop out all the product and to put it in the container. I'm sure you can see it's not the prettiest thing in the world but it beats throwing out half your product because you think there's no more left.
My little tip is to use a glass jar to store your debottled primer potion. I know a common thing is to use a plastic jar but I have always had the product dry out in those within a matter of weeks (no matter how tightly I close it). For this, I used an empty MAC Studio Sculpt Concealer jar. I saved it because I knew it would have a use. This container closes tightly and keeps the air away from the product! I wish they sold empty ones!
I have recently seen that the Sephora website has the Urban Decay Primer Potion in TUBE packaging and the product doesn't have a "Limited Edition" next to it. I'm a little skeptical of this one because I had previously purchased the tubed professional size (which I think was LE) but I found it dried in the tube because the cap wouldn't close tight enough. I hope they changed that!
Have you "debottled" your Urban Decay Primer Potion? What do you use to store the remaining product?
