كرات بن وا من فيفتي شيدز سيليكون ديليشس

The rolling balls inside make the sensation genuinely unpredictable, which is exactly what I was after. At 32g each they're light enough to wear for a while without any discomfort. Silicone feels smooth and cleans up easily too.

Wasn't sure about the free-roaming balls at first but that unpredictable roll is honestly the best part. The silicone is smooth and comfortable enough to wear around the house for an hour without any irritation.

At 32g each these feel light enough for all-day wear, and the silicone is genuinely soft rather than tacky. The inner balls roll around when I move, which makes walks around the house way more interesting than I expected.
