I see two distinct bottles for the men's fragrances from Maitre Parfumeur et Gantier.
I also see their site lists 16.6oz refills for most men's scents.
About the bottles...
One is smooth and flask-like with a narrowed base:

the other with an argyle pattern in the glass and a regular base:

1st. Are they both spray ? Or is one splash ?

2nd. Is only one bottle type re-fillable ? Or both ?

Thanks for any answers.
