I had several oil vails before. All of them of aluminum. They where small, light, and it was allways difficult to get the oil out of them for a blessing. So this time I bought a bigger one. Yes, it's much more heavy than the other ones. But the opening is much wider, so now it's easy to get the drop of oil out there for a blessing. The only negatv point is that neither the opening nor the closure are deburred and therefor are a bit sharp.
