Features:

• PERFECT BASE FOR DIY BALLOON COLUMN STANDS – These two bases have a middle hole of 2 mm (0.78″) in diameter which is perfect for similar size PVC poles. It won’t fit if your PVC pole is larger than 2 mm (0.78″).
• SAND, WATER, SALT FALLIBLE – Depend on where you will be using this base as balloon column stand. For indoor, it can be filled with water. For outdoor you need a bit heavy stuff fill up the bases, so we highly recommend using sand or salt.
• EASY TO USE – There is no trick or complicated instruction for using these bases. Just open the lid and fill it up with either sand, water, salt, or metal beads.
• ATTENTION– We don’t recommend using this for building a balloon arch. It might NOT be heavy enough to hold the balloon arch. We recommend you to using PartyZealot Balloon Arch Kit to build your balloon arch instead of these two bases.
