i used to have the smaller one. not bad quality, really users and not so much collectors. there is a yahoo group called leather and lead for jack and sap collectors. i might be interested if you want to sell them.
I have both. Used the large one as a LEO. If I didn't take my K-9 on duty with me, when I got off shift, she would come out of my house and run at me growling. I'd remove the sap and throw it clear across my lawn.. She would pick it up and chew it for about 10 minutes. It is covered in teeth marks. I wouldn't sell it for a million dollars. I've seen new unused ones for $25.00 or so.
