Customer Reviews

Based on 13 reviews

I love these tunnels. The rainbow color is subtle, yet still noticeably different from the other jewelry I wear. The tunnels are secure, comfortable, and lightweight. I have small, attached earlobes and feel the size of the tunnels looks good in proportion to my ears.

Since the tunnels I have are a 6g, the tunnel hoop earrings I own don't fit through them. However, regular hook-type earrings fit great, using those little squishy slide-on backings to keep them from sliding out.

TBJ customer service is amazingly responsive and helpful!

Love them

Both great quality and price. Will definitely be ordering from this company again

Okay I guess

They are slightly bigger than the gauge they say.

This is a great item, it's just my nipples are to wide for them.

Awesome tunnels

They look even better in person! I get compliments on them all the time. They aren’t heavy at all, it’s like wearing nothing.
