Mafex joints are designed to be very tight, so that the figure can hold poses well. However, this also means that they can be difficult to loosen when you want to pose the figure differently. Here are some tips for loosening Mafex joints:
-Use a hairdryer or heat gun on low heat. Apply the heat to the joint for a few seconds, then try moving the joint. Repeat as necessary until the joint is loose enough to move.
-If you don't have access to a hairdryer or heat gun, you can try boiling water and dunking the figure in it for a few seconds. Be careful not to leave it in too long or the plastic will start to warp. Again, try moving the joint after heating it up and repeat as necessary.
-Another method is to use ice instead of heat. Put some ice cubes in a zip-lock bag and apply them directly to the joint for a few seconds at a time. This will usually make the plastic more brittle and easier to break, so be careful not to overdo it or you may damage your figure.
