I buy this for my 6 month old who be now very distract while nursing and be also want to chew on everything . the clasp be sturdy and the pendant be flexible with a little give . it need to be wash from time to time because it collect fuzzy . my son like hold on it it and occasionally will give it a little chew . I have get complement from other mom on how pretty it be and they do not know it be actually a teether . this one look more like turquoise than Jade in my opinion because be very blue , not green . I love it . on I the pendant hang just below my chest so it be a long cord .
