Yea I might have to unless I can find something made out of butyl in a store.
Man shipping takes the fun out of online shopping, 15 bucks to ship 1square foot which is less then .3lbs, ill send them 75 cents for stamps and they can shove it in an envelope
I used 2 layers of the tape I have inside my 900 cups, almost too much...I had trouble getting them back together but I believe it helped the bass get tighter.
I'm pretty sure I didn't use even a square foot for both cups. $15 is a total rip-off for shipping...considering that I estimate that my shipping to Canada would be around $3 in a medium size bubble envelope.
