I bought 3 of these for my daughter's to have a bit of their grandfather with them. The necklaxe and kit are great but it took some modifying to use. Here's what helped me.

They each come with a kit to help put a VERY tiny amount of the ashes in them. I wound up having to rig the kit a little bit to make it work. Firstly, the pin it comes with is very hard to hold on to so by halfway through necklace one, I discarded it. Also, I had to cut the funnel twice. It was bigger than the necklace itself. I cut a bit of the tip off (carefully so I didn't cut too much) and then cut the funnel in half. You don't need something that big and it got in the way. Also, it comes with a small yet still sizable scoop spoon. The necklace holds probably enough ash to sit on the edge of the spoon. Make sure you don't get any fragments in the scoop or it'll block the funnel. Then, I used the enclosed mini screw driver and twisted it back and forth. Voila, the necklace was filled up in no time.
