30 Pieces Invisible Plant Pot Feet Risers with Non Slip Surface Indoor Outdoor Solid Corkwood Planter Pot Lifters for Plants Flowers

The cork itself is decent (can't really get a bad quality cork anyway). However I recommend against this product. All 30 corks are the exact same size, this was in the description, but I got tricked by the image, which shows corks in different sizes. On the other hand, the packaging is terrible. It came in a resealable package but was also taped up. It's pretty hard to remove the tape because I'm risking damaging the package. Even after I removed the tape, there are also some sticky leftovers on the package, making it a bit messy for storage. At the current price ($13.99), there are definitely some other better product to choose frim.

These were the perfect answer for keeping my flower pots off the ground, allowing them to drain properly.
