Besides using things I already own I also recycled one of the numerous IKEA bags I bought. IKEA Kassel is just 10 minutes away, I think that explains why I have so many ;)
- A blue IKEA plastic bag
- A navy blue plastic zipper, 23 cm
- Navy blue sewing thread
The pencil case measures 19 x 8 cm.
And yes, I own a lot of LAMY pens :)
