The cheapy metal/aluminum? lids that come with the wine are poor quality and I don't trust them. If you store your bottles in an upright position (as you should) they work great for protecting your beverages from the elements, etc. ## Frequently Bought Together - 12 Pack 38mm Growler Caps Growler Lids Poly Seal Screw Caps Poly Seal Growler Caps Compatible with 1/2 Gallon and 1 Gallon Glass Gallon Jugs Replacement for Homebrew Wine Making Beer Brewing, Black - Glass Jug, 1 gal (Pack of 8),clear --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/273593586-12-pack-38mm-growler-caps-growler-lids-poly-seal-screw](https://www.desertcart.jp/products/273593586-12-pack-38mm-growler-caps-growler-lids-poly-seal-screw) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-27*
