The split vs one-piece page decides the tool. This URL is how you mark the hook in the RFQ so we do not discover it on the sample.
RUUIPON cuts custom silicone molds in Shenzhen since 2018 for brand and Shopify buyers. MOQ 20 trays per design. Complete RFQs typically get a reply in about 24 hours. Prototype is commonly 3-7 business days after CAD lock. Drawing deposit ~$50 USD when we must model cavities.
Hidden Hooks Become Sample Fights
If the first sample looked fine, wait until later cavities before you approve a production sheet. Restock is where this failure shows.
