Some piercings can shrink when jewellery is removed making re-insertion tricky or uncomfortable. If you need to disguise a piercing, opt for a glass retainer which will make a piercing less obvious. It won’t be invisible but it certainly will disguise a little better! 
Our borosilicate glass is safe for healing piercings (when suitably sterilised) and for use during MRI scans. 
We also have little “freckles” available from NeoMetal! These textured ends work great with a labret in nostril piercings.
