As for those ones, I'm not sure but if you're in the market for some new ones, I'd recommend these:
Baies (it's burning next to me right now), Tubereuse and Mousses are my favourites so far. Very strong even when unlit. I'm getting doubles of those ones delivered next week plus Feu de Bois and Pomander so I'll be able to give you my views on them then. I actually wrote a post about them yesterday if you want to check it out.
+ Baies is good when you want something alive and fresh. It's a lemony floral. It wafts all through the house.
+ I absolutely love Tubereuse - it's gorgeous floral scent. Probably my favourite but then again, they're all favourites I have the ones in the red jar though so I'm not sure if they have a strong scent or not but it's doubtful.
+ Mousses! Oh my god, there is nothing like it. I feel like I'm in a deep dark forest when it's burning. If you're not into really raw and earthy scents though, you won't like it. I think it's amazing when you want to get away from florals.
