4mm Ostomy Paste Ring Ostomy Barrier Ring Stoma Leakproof Ring For Protect Skin

I haven’t figured out how to use this ostomy paste ring yet. It looks too small for my uncle’s ostomy, and I’m unsure if it will provide the right fit or seal. The product seems well‑made, but sizing appears to be an issue. I wish there were clearer instructions or guidance on how to apply it properly. At this point, I’m hesitant because it doesn’t seem suitable for his needs.
