I going to Helsinki and Tampere (Tammerfors) on a vacation, and would like som tips on shops selling armor modells and Vallejo acryllics paint.

Does anybody know of any shops worth visiting?

The one I know of worth visiting in Helsinki is T:mi Kuivalainen. They're located on Aleksis Kiven Katu 58, and are only open on Friday and Saturday from noon to 5pm. Here's his website: T:mi Kuivalainen

Hope this helps,
Mika
