This makes it more useful as you don't need to have as many sizes in your tool box. It shrunk down fairly quickly when heat was applied. I can recommend this product. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good product *by A***N on Reviewed in the United Kingdom on 31 March 2021* Good product ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It does the job and very well to *by D***S on Reviewed in the United Kingdom on 19 October 2019* Brilliant for what I needed it for --- ## 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/103251881-3-meters-heat-shrink-tube-3-1-ratio-glue-black](https://www.desertcart.jp/products/103251881-3-meters-heat-shrink-tube-3-1-ratio-glue-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-05*
