I have to agree with TM,

Syrian hamsters like Blaze are 100% solitary, they will fight to the death eventually if placed in contact with other hamsters.

Even if they are separated in time they can cause serious injuries which can be fatal in the blink of an eye.

Also it is highly unnatural and stressful for hamsters to meet, unless they are seeking a mate, stress in syrian hamsters can make the animal more susceptible to the bacteria which causes wet-tail. Wet-tail is fatal in most cases, even if treatment is seeked promptly.

Finally such meetings could result in unwanted pregnancies.

Syrian hamsters should only be allowed to meet when the female is in heat and for only 20-30 minutes under complete supervision by someone wearing thick gloves.
