It is a high quality, professional portfolio with a ring binding mechanism for the presentation and display of artwork. Burstproof rings are fitted to minimise the risk of rings opening accidentally under pressure when loaded to capacity with sleeves.
There is a Steel Bar in the spine to support the weight of the sleeves and the outside material is very strong and waterproof. The A1 Matrix Portfolio comes with a shoulder strap for easier carrying.
Matrix Portfolios are available in the following sizes: A1, A2, A3 & A4. Please note that Presentation Display Sleeves are purchased separately. Ideal for College Interviews & Professional use.
