Looking for the correct street to buy:
1. A white board a.k.a dry erase board (not huge, 1 meter x 500 cm is good)
2. a cork board or something similar where I can mount visuals with push pins, thumb tacks, etc.
Anyone know the street in Hanoi where I can find a selection of these items?
Let's go to Ly Thuong Kiet street, around number 42-48, there are plenty of choice and the price is reasonable. Go along Ba Trieu street, turn right when you get to Ly Thuong Kiet, shops are on the right side.
I don't remember exactly number of the shop but I know there are many shops that different boards available.
You can check 42 Hang Hom (it's near the end of the street cutting with Hang Gai). I believe it said "MICA" on the sign... This shop customises anything you want with acrylic sheets (which can be used for white boards), as well as cork boards, and fabric pin boards with one or two colors to choose from.
They have a laser system, which means you can also order stuff that needs to be engraved. The shop has various samples there, so you can point things out and write down the dimensions if the seller doesn't speak English that fluently.
If you've been in Vietnam long enough, you know that ANYTHING can be custom made!
Hope that was helpful. Happy hunting!
