✨ Why You’ll Love It

💎 The Detail
Bright and expressive, this crystal-topped design adds personality to a simple straight barbell. Wear it as the colourful focal point of your piercing collection or coordinate it with other rainbow-finish jewellery.
Choose your fit by comparing the listed measurements with jewellery that already sits comfortably in your fully healed piercing. The decorative topper and ball end have separate measurements, so check both when considering the overall fit.
Handle the crystal setting gently and avoid abrasive polishing products that could damage the coating. Check that the removable end is securely fastened before wearing.

How is barbell length measured?
Straight barbells: Measure the wearable bar between the two balls or attachments. Do not include the balls or decorative ends in the measurement.
Curved barbells: Measure the wearable section of the curved bar between the two attachments.
Nipple barbells: Measure the wearable straight bar between the two ends. For decorative nipple shields or specialised designs, check the product specifications because the wearable length can differ from the overall bar measurement.

Everyone’s anatomy is different. If possible, measure jewellery that already fits comfortably.
