I have the wax pencil like placer and they work pretty well,not from UMP but same same,you can find them cheaper on ebay or Aliexpress

I have a small bar of beeswax that I stick a toothpick in for a bit of tacky-ness on the tip.

I also have the pencil from UMM. It works OK for some items, but for really tiny parts which are longer than they are wider (such as fine hydraulic lines or thin cables) it has an issue with finding enough surface area to "stick" too. I also find it only supports so much weight, so the heavier a part is, the more difficult it becomes to grip it-- requiring more force to "stick" which can break fragile parts if you are not careful. In those cases I've had some success using "Silly Putty" formed into a tiny ball, and either attaching it to a fine point tweezer or using a wooden skewer cut down to size. Once the part is dry, I remove the "Silly Putty" The pencil is OK, but doesn't always work for every small part.
