I used thes in my installation for emerge in 2004. For a recent show I put them into small stacks. These stacks of small felt tanks seem appealing to me - so I thought I'd offer them up! They are $3 each [you can sew one onto something if you so desire] or you can get a stack. 25 for $50, 50 for $100 and 75 for $150. They come in bubblegum pink, hot pink and brown. Your tanks will come with a certificate of authenticity from me [because I can't sign each tank]. email me if you want some tanks, of have any other questions. these are approx. 3 1/2" x 5 1/4" each.
