Thermal vacuum former machine - works very well, only used a few times.
The heater element takes about a minute to warm up, and gets more than hot enough to melt / soften the plastic (few extra pieces of retainer plastic included!). The vacuum is very strong, sounds like a jet engine when you turn it on.
Leave the plastic in the melty state for about 10 seconds before pulling the vacuum seems to be the way to use the machine. Vacuum for about 5 seconds.
The beads are for placing your mold item into while the vacuum gets pulled. The beads are included.
