I would 100% recommend this company. I bought a load of frames which were accidentally the wrong size off a major online retailer, but really wanted custom mounts to frame the certificates. I came across Best4Frames when searching for custom mounts and was thrilled to find I could still use my A4 sized framed for my A4 sized certificates, whilst adding a 2.3cm mount around the edge to get the visual impact I wanted. Multiple colours of mounts available, fully customisable dimensions (to a point, you can only go so narrow), easy ordering process. Why I'm giving 5 stars? I placed my order the Friday afternoon before Christmas, and honestly, reading the delivery info, didn't expect to see them until January. They arrived on the Tuesday morning!!! In pristine condition, carefully packaged, and just perfect. Fantastic service, would reccomend!
