Review on Silicone Resin Casting Molds for Button Shapes - DIY Dropping Glue Epoxy Mould for Handmade Craft Pendant Mold and Jewelry Keychain Making Supplies (Round Button) by Kristen Simpson

Button shape works well but is thinner than most other shapes I've bought. It works so well I have already purchased 3 more of the same molds so I can button button entire shirts in less time. Currently this listing says it's unavailable (maybe I bought the last one) but if it's back in stock I'd say it's worth the $6 I paid but I wouldn't pay more just because, as I said, they are a bit thinner than I would have liked.
