Silicone Replacement Bulb for Metal Pipette 2 inch | Size Large
This is a silicone bulb that fits a 2.75 inch X 5/8 wide inch metal pipette. It fits tightly around the pipette and draws in the hot wax well. You get good control with wax disbursement as well. Use these to replace your old rubber bulbs when they no longer work and have degraded due to heat. This bulb is made with Silicone and therefore the heat does not degrade silicone like the latex and rubber alternatives, which are cheaper but will not last as long.
These replacement bulbs actually work better than the rubber bulb that comes with the metal dropper because they hold more wax and offer a bit more control. They are also don't get soft when heated, since they are semi-clear you can see the medium inside the bulb and maintain their shape.
These are the best option I have found thus far for working with encaustic media application.
