It seems that the lid of the included paint cup may become stuck due to the effects of air pressure during shipping. In this case, please try the following method.
・Slowly lift the lid up without turning it.
- Warm the cup and lid with a warm steamed towel.
-Wrap the cup in a towel and use large pliers to pull the lid straight up.
*Other customers have reported that they were able to open the lid easily by lightly hitting it with a rubber hammer and vibrating it, but please be careful as we cannot be held responsible if the lid becomes distorted by hitting it.
