tershine - Decals in different colors, the sizes I have are 15 / 20 cm. Of course, there is always a bunch for every order for free! If you want to order separately in other sizes, please send an email to email@example.com.
Also the sticker "PLEASE DO NOT PET" is available in white at 8 x 3 cm
Of course, I can offer my logo for print if you want to do it yourself (which is preferable).
