im sceptical when buying a 10cm unsexed t. For reasons such as the person
selling the spider either knows it a male and wants to make himself a extra 100 buck.
I think if it someone that is selling a unsexed spider has a responsibility to try keep
a molt( if possible) to give to the buyer so he/she can confirm the sex.
At time if u buying a unsexed t, ask for a molt(if possible) and if can get a molt
its a risk u taking.
personaly i dont even look at unsexed ts to buy.
