Maker discloses silicone construction; dishwasher safe. THIN SPOT: maker retail page itself only states 'silicone' — 'FDA food-grade' claim comes from third-party retailers, and maker wholesale page links a BPA-free certificate. Owner follow-up: confirm food-grade wording with Masontops in writing before launch. In stock at maker (both mouth sizes) on 2026-09-20. Airlocks-only add-on, distinct from the store's existing Complete Fermentation Kit. Image visually verified as the exact product by the sourcing worker.
