In Brisbane, Palador Fumior Salon (a Cuban Cigars and Coffee Salon -- you can smoke [cigars only] there) has boxes for $5.00 & $10.00, and the money goes to their charities. Several good sizes.
Fish Lane and Merivale St, South Brisbane (diag opp the Bris Convention & Entertainment Centre). Filip is the proprietor.
Open morning and lunch.
(Interested in having Sat morning ukulele/CBG sessions there too).
Brass will match any brass fittings on your box.
Nickel will match any nickel or chrome fittings.
I was also able to get a 25mm nickel eyelet and 15mm brass from a local canvas maker. Regards John D
