Magigoo is designed to be applied on a clean, dry and room temperature build plate, unfortunately we do not always have the patience to wait for the build plate to cool down :(
Magigoo dries extremely quickly on a hot build plate, and can often lead to pulling out the little sponge, this is a replacement so you can enjoy your Magigoo down to the last drop.
Note: this item is only a single applicator (despite the photo showing two)
