Angel and Demons blotters

Anyone heard of these? I got a buddy who's got some he told me that 1 tab sent him flying. Also does anyone know if sending blotters in the mail overseas ruin the tabs? If not how should they be kept?

 

sending oversea doesn't ruin them they should just be carefully handled

 

My friend said he's got some blotter with an angle on it.

 

When you mean carefully handled how they are stored in the envelope or getting located by cops? I'm thinking of having then in aluminum foil inside a card.

 

dont put any metallic object in the envelope. putting them inside a letter or card should do.
