It was like the bag was interfering with it snapping in place. ### ⭐⭐⭐⭐⭐ Auto clave compatible *by T***D on 25 June 2023* The sleeves work really well. Some people have said they don't secure well at all but I don't think they are actually clicking the 2 pieces closed. They are very difficult to pry apart once you close them. Only downside is the cheap foam filter on top. I added some micropore tape on top of the filter and it works fine. ## Frequently Bought Together - Biomed Solutions Mushroom Grow Bag Cap and Ring for Cultivating Sealing Cotton Filter Cover 40mm(Pack of 9) - TonGass 60-Pack Autoclavable Mushroom Growing Bag Bulk with Microporous Filter Patchs - Large 8"x5"x20" Extra Thick 80 Micron (=3 Mil)| Mushroom Cultivation Spawn Supply Myco Bag Bulk Substrate Bags - 3M Micropore Tape 1530-1 (2 rolls) 1 x 10 yards --- ## 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/629353716-biomed-solutions-mushroom-grow-bag-cap-and-ring-for-cultivating](https://www.desertcart.tn/products/629353716-biomed-solutions-mushroom-grow-bag-cap-and-ring-for-cultivating) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-17*
