Review on FineGood 8 pcs Pencil Extenders: One Head & Dual Head Metal Handle Pen Holder Lengthener – Ideal School, Office and Art Writing Tool by Kim Kawana

Seller has listed conflicting sizes on the seller page and some sizes appear to be incorrect. First a set of six holders of the same size, suitable for pens with a diameter of about 7mm. They fit perfectly with Faber-Castell Polychromos. The hexagonal holders by Faber-Castell Albrecht Durer are too big for them, as are the 8mm Caran D'Ache Luminance, Museum Aquarelles and Derwent Lightfast. The two large reversible holders are available in two different sizes. The narrower one appears to be the same size as the single-sided holders, and the zip-ties used to tighten the grip of the pins (shown end-to-end in the photo) are interchangeable. The big end appears to be closer to 9mm. It's definitely larger than Derwent's 8mm pencil extender (bigger, silver) and will fit 8mm pencils accordingly, but with one side free (you can put a layer of tape on the pencils to secure them). 7mm holder tested with: Faber-Castell Polychromos: fits well. Caran D'Ache Supracolor Soft (Hexagonal body): Pretty good Faber-Castell Albrecht Dürer (Hexagonal body): You can stuff the pencil tail a little beyond the silver band, but don't adjust the length. Not recommended. Caran D'Ache Luminance, Museum Aquarelle, Derwent Lightfast: the same as Dürer, but even more marginal. I would not recommend them for pencils listed as 8mm or larger. 0.9mm Faber Castell Albrecht Dürer: Slightly loose fit. Can be used in a pinch, but the 8mm Derwent holder works better. Derwent Museum Watercolors: about the same. Caran D'Ache Luminance: Looser than the previous two - stick it on or skip it. Derwent Lightfast: Same as Luminance. Conclusion: Great for 7mm round pins like Polychromos. All eight owners worked well with them and represented a good business. It's neither fish nor meat for 8 mm pencils - just too loose with the wider holder in the turning example and too tight with the narrower holder. If you have 9mm wide pins the wider end might work for you but the grades I have don't match. Bilateral extension cords are noticeably heavier. You'll probably have to take out your pencils to sharpen them.
