Foot Protector Installation Tips
Installing the Foot Protectors is fairly simple. All you need to do is drop them into hot water ~80° C for around 10-20 seconds and this will make the plastic pliable, almost like Blu-Tack.
Whilst pliable, simply slip them over the bolt head and squeeze together whilst the plastic cools.
Removal is a little more difficult (for good reason). You can dip a sponge in hot water and apply to the plastic, then use a flat head screwdriver to pry open the slot, but do be careful not to slip as it could damage both you, your doll and the protectors.
