What seems like forever ago I sold my MM B hamorii (it was a smithi back then). I don't even recall how long its been, but he got a sac and since that male had sentimental value I just had to get some of those slings! He gave me a great deal and I now have 15 of the tiniest slings I've seen in my life. They are about 1/4". Wish me luck keeping them alive!
