B4 WHITE SELF-SEALING ENVELOPES 250PCS 

B4 - (250 x 353 mm)

Self-adhesive bonding (SK) - this is a latex-based bonding. The adhesive is located on two bonding surfaces (on the opening flap and 
the counter-flap). Bonding is achieved by contact between both flaps. Manual handling is therefore particularly easy and 
uncomplicated. However, the durability of the bonding - depending on the method of storage - is limited to one year.
