Ideal for clothes, brochures, photos and other literature that needs to arrive in pristine condition ABEPLUSR5 envelopes measure 265mm x 357mm. Each envelope is pre-creased to allow you to select a capacity of up to 50mm to ensure a snug, secure fit for your items. At maximum depth the internal dimensions are 250mm x 340mm x 50mm*. The creases make it quick and easy to customise the envelope size and a peel and seal adhesive strip is included to make packing simple and fuss free. These envelopes are so strong and secure with a tamper-proof seal, reinforced corners and seams and durable puncture and tear resistant card, that the integral easy-open tear strip is important to allow customers to access their goods. A great alternative to bulky boxes that need void fill and cost more in postage fees. *Effective size decreases with increasing thickness
