i know what you mean about fixed income i get my check on the 3rd and this month there is way more month than money :) i have never done the etching is it hard and are there fumes? on oxygen have to avoid strong smells
I'm sorry but I really don't know. I have not used it. I have had it for a while thinking I would use it but I have so many other crafts going , So I thought I would let some one else use it. and enjoy it. I knit & design jewelry. I just looked on the package and it said ( No Toxic - No Harmful Fumes & No Skin Irritation ) Thanks for asking, Barbarap
