Reusable silicone cupcake liners can save you money, because you are not buying and throwing away them all the time. You also don’t have to worry that you will run out of cupcake liners. It is a good idea to have them handy when you realize that you are out of paper liners.
Silicone cupcake liners are not suitable for bakeries. Another con is that cleaning may take too much work after big gatherings. Some cheaper brands are not made of pure silicone.
It would be a good idea to have both, because the silicone cupcake holders are more suitable for everyday use, while paper cupcake wrappers are more convenient for special events.
