Check bases and threaded pieces
Confirm what stays attached and what comes apart.
Verify the full base
Choose a product intended for anal use with a clearly flared base that remains outside the body. Check the widest insertable diameter and the base separately. If the listing leaves those details unclear, confirm them before buying. See Planned Parenthood’s sex toy guidance.
Look at trim and attachments separately
Check the manufacturer’s instructions for threaded pieces, decorative inserts, and removable tails. Set a product aside if a part is loose, rough, or visibly damaged.
