I have 3 different designs for my pins with each being different sizes but are very close in size. They are nice and brightly coloured. With a rubber pin back. I have 1 Original artwork which is my Exotic Bird, this is 3.2cm * 2.5cm. Then, I have 2 Anime Fanarts one being the Luffy 5th pin, which is 4cm * 3.6cm in size. Lastly, the Zoey (from Mew Mew Power) which is 3.9cm * 3.5cm in size. I am really happy with the colours of my pins, they do look nice if I say so myself 😅 There is a blue protective film, which you can take off yourself, whenever you wish.
