An alternative to the adhesive rings and the Jade Stone is the Crystal Plate.
Depending on your preference, you may use such a surface or the disposable trays. The Jade stone, as well as the Crystal Plate are perfect for holding the adhesive and resting your tweezers when not in use.
They can easily be cleaned with adhesive remover and repeatedly used. You may also let the adhesive dry on the adhesive holder and then remove it with a razor blade.
