The Thames & Kosmos Steintrommel Nachfüllpackung

The one-pound bag has plenty of rocks to get another full cycle going, and my kid was thrilled to spot the tiger’s eye right away. The mix feels like real variety, not just filler.

My daughter finished her first batch and immediately asked for more rocks, so this refill was perfect timing. The mix has a nice variety of textures and colors, and the tiger’s eye pieces polished up really nicely after a couple weeks in the tumbler.

The one-pound bag of tiger’s eye and rose quartz was a hit—my son sorted through every single piece before we even loaded the tumbler. The variety feels generous for the price, and the rocks came out nicely polished after a couple weeks.
