Our 3D hand model set contains seaweed extract, plaster and silicone clay. It can enhance the relationship and promote the communication between each other. Its use is very simple: prepare the clone powder and room temperature water (powder water ratio of 1:5) into the bucket, stir well until there are no particles. Pour the clone powder into a bucket at once and stir quickly within 60 seconds. Dip your hand into the clone powder liquid, hold it still for about 5 minutes (be careful not to touch the bottom of the bucket), wait for the liquid to solidified into an O-bomb (about 5 minutes after the model is completed, you can proceed to the next step), gently swing your arm to let air in and slowly pull your hand out. After curing, pour out the whole, break off the glue, and gently remove the hand mold. After solidifying, pour it out as a whole, break off the glue, gently take out the hand mold, after taking out, use our tool [bamboo skewer sandpaper] to trim it slightly to make the model more beautiful.
