## Overview

The Product Nation A3 Black Foam Board pack includes 10 sheets of 5mm thick, acid-free foam boards, ideal for a variety of creative projects. With a focus on quality and customer satisfaction, this family-run business offers a lifetime guarantee and exceptional service.

## Description

Our 5mm thick Black A3 Foam Board is great to use for a variety of tasks including mounting photographs for school or art shows, displaying important presentation visual aids, displaying wedding table seating plans and also for 3d model making. The foam core is coated in acid free UV protected paper which means the board will not yellow over time and the tightly packed core is easily cut with a standard craft box knife. Our A3 black foam board is packed in quantities of 10 sheets and measures 297mm x 420mm.

Review: Did the job. - This did the job of displaying some jewellery items with pins.
Review: Not accurate A3 - It may be important for some to know that these boards are inaccurately cut and are marginally bigger than A3 so have to be trimmed down if that's what you need. They vary slightly in size too between boards. For the most part they are 29.9cm (should be 29.7 cm) by 42.1 cm (should be 42cm). They really should state that measurements are approximate and that some trimming may be needed to get these to be exactly A3, for example when mounting photographs. I suppose at least they are over sized rather than under! I'm not happy that I've got to trim each one of them to be A3 though, hence only 2 stars. Good part is they are very well packaged in a stout cardboard box and therefore were not damaged in transit.
