Hello,
New member here. I needed a small bag to carry water, wallet, camera etc. and I could not decide on a tank bag and was worried about scratches etc. For a quick solution I ordered this $5 fanny pack from Walmart and It fits my FJ's Corbin seat perfect and rock solid for short trips and doesn't harm the seat or paint in any way. Today I carried 2 bottles of water, my phone, my wallet and my park pass. Hope this has not been covered before or is in the wrong category. PS I don't work for Walmart ;)
