Although we wish there was an adhesive to simulate the peel off of market jars but that’s okay ### ⭐⭐⭐⭐⭐ Review *by L***D on 15 January 2026* They work like they should! They do kind of stick together, so just carefully peel them apart, line up with the top of the jar, and then close the lid. Let them sit for a few minutes before trying to open them so they seal properly. I thought they weren't going to work for me at first, but then I let it sit and opened the jar again and they were perfect. I've already purchased another box! ## Frequently Bought Together - 70 mm Foam Lid Liner Pressure Sensitive Seal Round Jar Sealer Bottle Seals Heat Resistant Foam Cap Torque Activated Safety for Protection Safety Jar Cap Bottle Vial Tamper Gasket Kit(100 Pieces) - Jars with Lids, 48pcs 8 oz Plastic Containers with Lids Pen Labels Leak Proof BPA Free Airtight Refillable Clear Small Containers Storage Jars for Storing Dry Food Makeup Slime Honey Jam (8oz Black - 50 Pack 4 OZ Plastic Jars Round Clear Cosmetic Container with Black Lids, Eternal Moment Slime Jars for Lotion, Cream, Ointments, Makeup, Eye shadow, Rhinestone, Samples, Pot, Travel Storage --- ## 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.tn/products/386833850-70-mm-foam-lid-liner-pressure-sensitive-seal-round-jar](https://www.desertcart.tn/products/386833850-70-mm-foam-lid-liner-pressure-sensitive-seal-round-jar) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-10*
