I ordered ten and have only been able to separate them by curing epoxy onto metal brackets. Not happy the work involved, but they are very strong! If AE has an ability to break them one by one, I would like to see spacers. Anyhow, you must use metal epoxy to mount to metal surface. No other substrate nor adhesive works. Use caution handling, and of course keep these and all hi-power magnets out of reach of children!
