LOL this leads to a funny story.
When I first decided to run a poker ;league the first thing i did was buy some chips. I came across those exact chips super cheap and bought them.
I didn't much care for them, and after finding a few poker boards decided to go with super diamonds instead.
So I gave my 4 year old daughter a bunch of those suited chips cause she kept wanting my super diamonds.
Well I decided to lable the sd's and my daughter saw me doing it and she wanted "some stickers to" so i gave her a page of lables, and imitating daddy she did this.
so in short yeah they can be labeled and the label actually doesn't fit to bad, however it does cause stand out further than the chip since they are not recessed.
