## Emma's take

Cast your own glow-in-the-dark keepsake in twenty flexible minutes.

This is the refill for anyone who already owns a Bananakit casting set and wants another round, or wants the glow-in-the-dark color for a keepsake that reads playful rather than clinical. The spec sheet lists a twenty-minute cure, fast enough to hold attention without rushing the mix. Skip it if you're starting from zero, since a refill assumes the kit's tools are already on hand. For the best cast, work through the ninety-second mix and five-minute working window before it sets, then let the mold cure undisturbed for the full twenty minutes.

## Frequently asked questions

## What's included in the Bananakit glow-in-the-dark casting silicone refill?

This refill ships with 150 ml of base silicone, 150 ml of catalyst, and 10 g of luminescent yellow color powder, the same 300 ml pour as the original Bananakit Complete Kit. It's the compound only, so keep your existing casting tools and mold on hand.

## How long does the casting silicone take to set?

Plan for about 90 seconds to mix the base and catalyst, a 5 minute working window to pour, and a 20 minute cure before you can handle the finished cast. The result is a flexible, durable piece that keeps fine detail.

## How should I store the base and catalyst between uses?

Keep both bottles tightly capped and stored at room temperature away from direct sunlight. A refill this size covers one full 300 ml pour, so reseal what you don't use right away to keep the next session ready.

## Does the glow-in-the-dark color actually glow?

Yes. The color powder charges the silicone with a vivid yellow finish by day and a soft glow after dark, the same luminescent pigment used across the Bananakit line.

## Will this refill work with my original Bananakit Complete Kit?

Yes, it's the official Bananakit refill compound, made to the same medical-grade Italian manufacturing standard as the kit you already own, so it pairs directly with your existing mold and tools.
