Black diecut box FAQs
Are black diecut boxes black inside?
Standard black diecut boxes have a plain inside. The full black diecut boxes (B237, B238, B239, plus the A5 B236) are black on both sides.
Do they need tape?
Not to assemble: the sides lock as you fold. Add a seal sticker for security.
Which black diecut box fits a satchel?
See the Satchel column: many sizes up to 240 x 150 x 60mm fit a small satchel and the A5 fits a medium satchel.
Do you have black tuck front boxes?
Yes. See premium full black tuck boxes.
