Review: resilient with color quality. - multi 5x .019x12" TSF tough super flex quality color and brightness, resilient sofar messing around, specifically feeling it when it bends ( however Not tried super tight radius sofar but feel confident.) first brand I tried cracked easily and was much duller dimmer and couldn't be worked into my bow sight pin TUBE and wrapped with excess on the side without cracking. I will report back after I install these on a bowsight (axt head hunter) I like the clean look of the tube style pins on this sight (AXT)which need to be threaded through tight 90* and potentially be used to remove pieces of the first brands garbage filament by pushing its stuck pieces out. Friends cant believe there's nothing energizing these aside ambient light. showed the fibers to friends at party and 3 of them immediately placed an ordered (some just as eyes for art piece ) some for their target sights! Review: Great fiber, takes forever to get shipped though - The product is awesome...probably the best and most consistent out there. However, it takes FOREVER to get. Through desertcart is over a week, even with Prime. On their website, takes close to 2 weeks even if expedited shipping is selected. ## Features - Bright - Fluorescent colors stand out against your target - Durable - Won't fade or crack over time - Flexible - Easily bends around sights and pins - Customize - Use colors you prefer on your sight - Standard sizes - Fits all bowsights and sight pins ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009IV88BU | | Best Sellers Rank | #265,522 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #461 in Archery Bow Maintenance Accessories | | Brand | Nanoptics | | Brand Name | Nanoptics | | Color | Multi - Green, Yellow, Red, Blue and Hunter Orange | | Compatible Devices | Compatible with all devices | | Customer Reviews | 3.8 out of 5 stars 43 Reviews | | Item Display Dimensions | 12 inches | | Manufacturer | Nanoptics, Inc. | | Manufacturer Part Number | 010TS-12P | | Mounting Type | Bow Sight Mount | | Night vision | No | | Sport | Archery | | Sport Type | Archery | | UPC | 608729736219 | ## Images ![Tough Super Flex Replacement Bowsight Fiber 12" (Pack of 5) - Image 1](https://m.media-amazon.com/images/I/61YlG4s5NrL.jpg) ![Tough Super Flex Replacement Bowsight Fiber 12" (Pack of 5) - Image 2](https://m.media-amazon.com/images/I/515sgLkD64L.jpg) ![Tough Super Flex Replacement Bowsight Fiber 12" (Pack of 5) - Image 3](https://m.media-amazon.com/images/I/61QkO8lxONL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ resilient with color quality. *by T***Z on October 17, 2023* multi 5x .019x12" TSF tough super flex quality color and brightness, resilient sofar messing around, specifically feeling it when it bends ( however Not tried super tight radius sofar but feel confident.) first brand I tried cracked easily and was much duller dimmer and couldn't be worked into my bow sight pin TUBE and wrapped with excess on the side without cracking.

However, it takes FOREVER to get. Through Amazon is over a week, even with Prime. On their website, takes close to 2 weeks even if expedited shipping is selected. ### ⭐⭐ You’ll be BLUE alright! As in SAD Blue😢 *by J***E on April 7, 2026* Just ok fibers, If you’re looking for Blue, This is NOT what you’re wanting to buy. The Blue in the advertising picture is NOT what your going to get. Like someone mentioned in another review IT’S like fishing line. As a matter of fact I’ve seen Bluer fishing line. The other colors are ok. Bought True Glow and they are AMAZING, but I couldn’t find long enough lengths to fit my older Trophy Ridge vertical pin sight. These are long enough but don’t hold a candle to True Glow’s. And BLUE is just NON existent. Well after further review, I was sent the wrong size, WAY smaller than .019 Not impressed, buying from Bullseye on the bay of e. Much better product AND they will cut whatever length you need. --- ## 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.gr/products/6207939-tough-super-flex-replacement-bowsight-fiber-12-pack-of-5](https://www.desertcart.gr/products/6207939-tough-super-flex-replacement-bowsight-fiber-12-pack-of-5) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-09*
