It works for me Etrain.
My wife uses this glue (hydrogenated oil) in her coffee. We buy it at Costco. It came ( they are now using a container without the handle) in the same container as the Nestles. It is my opinion that the container is worth more than the product they fill it with. I saw the same value in the container as you did. I have used it allot at Pismo beach.
It worked well before I added the steel extension ( I think I will change it to an aluminum extension and make it a little wider, the steel makes it lttle out of balance and top heavy) but the extension allows you to go deeper into the sand. I drilled 3/8 dia holes to drain the sand. They do not weaken the container in any way. Be sure and make a couple of cuts on the top edge above the handle and fold down the plastic (about 1 or 2 inches wide). This will give you a comfortable place to rest your thumb as you scoop sand. I have collected about ten of these containers, thinking that they may not hold up under allot of use. However after using the original on for about six months, it shows no sign of failure.
I hope this will be helpful to you and others.
