Additional information and photographs for any item upon request, but
please have serious intent to purchase and not just being a looky-loo as I
field a lot of requests and it takes a lot of time to process.

I'm happy to negotiate a bulk price for multiple items. Your purchases are
always packed efficiently with superior care and materials. Shipping is
from California. Local pick-up is highly encouraged (you get to shop my
inventory in person). International purchasers are always welcome.

As always, please send inquiries to me directly via e-mail at <
sellam.ismail at> for fastest response.
