I use mine for 4 and 8 inch bottles. They work really well for our products which are oil based. **Q: Will these fit a 4oz jar?** A: From the ones I've ordered definitely not. They only fit like 10 gram containers ## Frequently Bought Together - Happyupcity 100PCS Seal Pressure Foam Self Adhesive Gasket Leak Proof Lid Lining Cap Sealing Silm Waterproof Membrane for Cosmetic Bottle Cover Liner Holder Snack Storage Container(2.7cm/1.1inch) - Surgical Grade Blades #11 10pcs Sterile with #3 Scalpel Knife Handle for Biology Lab Anatomy, Practicing Cutting, Medical Student, Sculpting, Repairing - Olympus Myco 97% Pure Gypsum Powder, 1 lb – High Solubility Calcium Sulfate Dihydrate for Soil, Gardens, Lawns, and Mushroom Substrate --- ## 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/267234481-100pcs-safety-seal-pressure-foam-self-adhesive-gasket-leak-proof](https://www.desertcart.jp/products/267234481-100pcs-safety-seal-pressure-foam-self-adhesive-gasket-leak-proof) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
