My 4th Marty's mold. Great product. Shipping takes 4-6 weeks to get here unfortunately but it's worth the wait. I'll be back.

Only reason i gave it a 3 star is because of the struggle to successfully make the balls. Was only able to make 4 balls.
Im sure with more practice I should be able to make them consistently.

Great round ball molds! Makes full pours easy. They come out perfectly round.
