Specifications Material: Paper Size: A3 Color: White Weight: 540 Packing Includes 12 * Picture Mounts A3 Review: Well recommended - It’s always a risk ordering something like mounts, due to the potential damage they can get during delivery. But these arrived in perfect condition in a large box and all inside a plastic wallet! The mounts themselves were perfect for framing. The colour was good. I used a backboard too, so together it was super sturdy. Would definitely order again. Review: Great quality - Great quality. I’m a practical storage wallet. ## Features - 【12 PCS A3 Mount for A4 Picture】: The package contains 12 pieces of A3 photo frames mounts, the quantity is enough to meet your needs.

But these arrived in perfect condition in a large box and all inside a plastic wallet! The mounts themselves were perfect for framing. The colour was good. I used a backboard too, so together it was super sturdy. Would definitely order again. ### ⭐⭐⭐⭐⭐ Great quality *by C***E on 10 February 2026* Great quality. I’m a practical storage wallet. ### ⭐⭐ Fit for A4 prints no good - not enough tolerance *by B***E on 19 December 2025* Fit for A4 no good... Gap is almost exactly A4 . So not good if you have A4 prints. Prints must be larger . Otherwise, yep it fits in an A3 frame and would be good with a centered print on A3 paper ... But that seems to defeat the object (?) --- ## 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.sn/products/587417185-adertos-picture-mounts-12-pcs-a3-white-picture-photo-mounts](https://www.desertcart.sn/products/587417185-adertos-picture-mounts-12-pcs-a3-white-picture-photo-mounts) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-01*
