Its part number is 91195.This item comes as pictured and does not include any additional parts or accessories.Specifications:Manufacturer: DykemPart #: 91195Item Weight: 1.58 ouncesProduct Dimensions: 6.8 x 0.5 x 0.5 inchesColor: ClearPoint Type: BulletLine Size: 2 millimeters Review: Not easy to get off plastics at all and can't see it after it dries and wears in a bit Review: To help mitigate bird strikes, I used these clear UV markers to draw a vertical pinstripe pattern on a series of windows in a bedroom (lines drawn at a narrow 2 1/2" spacing). 5 months later, it appears to be working - not a single strike (whereas previously I had a strike every month, at least). The clear stripes can be seen, but are not obvious. I applied the marker to the inside surface of my insulated windows. For bird's optimal visibility, I am reading that it is recommended to apply UV patterns to the outside surface of the window. I have not tried this yet. (I have concerns over the durability of the "permanent" marker being exposed to rain and snow, and am also concerned about dirt accumulating at the linework. But, next spring, I'll give it a try on the exterior to see how well it performs. Will keep you posted.) ## Features - Permanent UV Marker with Medium Tip Size Clear-Invisible - 1 Each - Medium - Clear-Invisible ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007ID3RT8 | | Best Sellers Rank | #147,831 in Office Products ( See Top 100 in Office Products ) #1,371 in Permanent Markers & Marker Pens | | Brand | Dykem | | Color | clear | | Customer Reviews | 4.1 4.1 out of 5 stars (68) | | Date First Available | 14 June 2016 | | Grip Type | Contoured | | Ink Color | Clear | | Item Weight | 23 g | | Line Size | 2 millimeters | | Manufacturer | Itw Dymon | | Manufacturer Part Number | 91195-1 | | Material Type | Plastic | | Number of Items | 1 | | Point Type | Medium | | Product Dimensions | 17.27 x 1.27 x 1.27 cm; 23 g | | Size | 1 Count (Pack of 1) | | Tip Type | bullet | ## Product Details - **Brand:** Dykem - **Ink colour:** Clear - **Number of Items:** 1 - **Point type:** Medium - **Recommended uses for product:** Writing ## Images ![UV-Marker , Permanent, Bullet Tip, Clear - Image 1](https://m.media-amazon.com/images/I/51iBn-u+XdL.jpg) ## Questions & Answers **Q: Will humans be able to detect this if I use it on glass windows backed by bright (or dim) sunlight? (Hoping to deter birds).** A: Humans should be able to see the marker. Although the ink is virtually transparent, the marking will still be slightly visible in the form of a residue. **Q: Will this stick to polyethylene plastic?** A: i used on rubber **Q: Can this ink be used on nonporous surfaces?** A: I believe so. It should dry just like any other marker and stay visible **Q: Is the ink completly invIsible?** A: yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***N on 20 March 2024* Not easy to get off plastics at all and can't see it after it dries and wears in a bit ### ⭐⭐⭐⭐⭐ Review *by T***M on 7 December 2020* To help mitigate bird strikes, I used these clear UV markers to draw a vertical pinstripe pattern on a series of windows in a bedroom (lines drawn at a narrow 2 1/2" spacing). 5 months later, it appears to be working - not a single strike (whereas previously I had a strike every month, at least).

The ink is transparent, however on certain materials it is not invisible and can discolor where it left marks. If you were hoping for an invisible marker, this won't do the trick. However it is very UV reactive and produces a bright white color when exposed to UV. Does have some fumes when using, so avoid small enclosed spaces. ## Frequently Bought Together - Dykem Permanent Industrial Marker, Ink-Based, Clears Color Family, Medium Tip, 1 EA 91195-1 - 1 Each - edding 8280 securitas uv marker - colourless - 1 pen - round nib 1.5-3 mm - black light marker - for hidden markings on almost any material - security marker, invisible ink pen, magic pen, geocaching - SAKURA Pen-Touch Paint Markers - UV Marker Pen for Black Lights - UV Visible Ink - Assorted Tips Size - 3 Pack --- ## 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/254498448-uv-marker-permanent-bullet-tip-clear](https://www.desertcart.tn/products/254498448-uv-marker-permanent-bullet-tip-clear) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-01*
