Apparently they are called as such. I just call them BBS badges.
The bigger ones are for sylenthermit09 and me. They are about 7 cm x 5 cm. Painted with a mixture of silver acrylic and poster paints, and finished with gloss varnish. I forgot how many layers there were. As you can tell, the one on the left didn't had a smooth painting process ( they look kinda weathered... wasn't my original intention... ). Just need to add in the pin backs and I will be done.
The babies are about 3 cm x 2.5 cm. They are for the charms. Still in the 1st stage of modeling.
Anyway, sylenthermit09 suggested to open this up for commissioning. So tentative information as follow:
for the default one ( the 7cm x 5 cm ), WITHOUT postage or pin back.
I might change the price a little if I figure out the proper way to add the pin back and offer the full thing.
for custom sizes, WITHOUT postage or pin back.
I have to scale up/down to make new templates so that I can make new sizes. Note about material
The whole thing is made entirely of air dried clay. It is light, and will break if you put a ton of dead weight on it, like almost everything else. Paint has been mentioned above. It should be waterproof with the varnish, but I have never really tested it out. The clay (after being fully dried out) does float on water, but with all that paint and varnish, I'm not too sure anymore.
Please drop a note if interested to discuss more.
