If you know your size make sure you tell them you want it that size or they will make it 7/8 smaller . I have not washed it yet but I am sure it will be fine. I hate the cheap replacements and the edges are made of cardboard that break or bend. ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on October 29, 2017* It's great --- ## 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.co.uk/products/87487309-23-1-2-x-23-1-2-x-1-lifetime](https://www.desertcart.co.uk/products/87487309-23-1-2-x-23-1-2-x-1-lifetime) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
