Check the base on every piece
Inspect each piece rather than assuming the bases match.
Look at the base from below
Use devices designed for anal use with a broad flared base or retrieval feature that keeps them from slipping inside. See Planned Parenthood’s toy safety guide.
Check the surface and joins
Set aside pieces with cracks, chips, rough seams or loose decorative details. For more on glass inspection, see the glass inspection guide.
Stop for pain or bleeding
Use compatible lubricant and stop for pain or bleeding. If an item is stuck or cannot be reached, get medical help promptly.
