The milk jug is not just a beautiful container for milk :)
Fill the inner surface with watercolor, acrylic paint, etc. Using colored pencils, gel liners, pencils, ballpoint pens, etc., paint just the outline or color the entire surface. Be creative as you wish.
 
The following sizes are available:
6cm x 5.2cm (HxW)
8cm x 9cm (HxW)
10 cm x 8.7 cm (HxW)
12cm x 10.4cm (HxW)
 
Other sizes upon request are possible.
 
I also recommend backing paper. All stencils (including existing ones) can be filed neatly and dust-free. 
You can also find this here in the shop.
 
Depending on the production process, there may be adhesive residue on the stencil. It is not a reason for a complaint as it cannot always be avoided.
 
The self-adhesive stencils can be used multiple times. Carefully rinse off any paper and paint residue under running water. Always stick it back onto the carrier film and store it away from dust. Under no circumstances treat with heat (hot air dryer). Protect from sun rays and heat.
 
The self-adhesive stencils are designed and manufactured in every detail by Schlichtbunt.
