I have ordered a 6oz bear from betterbee many times. In bulk, shipping is free(200 or 450 count). I sell loads of them. I might try these 4oz'ers, but filling them can be a pain in the butt.
In looking at both web sites, they may be same bear. One is listed in fluid onces, the other I think is by weight. So, does 4 fluid oz equal 6 oz. by weight?
