## Emma's take

Two molds, one sachet, zero guesswork.

This is the official refill sachet for Bananakit clone kits, made in Italy to dental-grade standards. One 453 g sachet gives you enough alginate for two complete molds, capturing detail down to fingerprints and fine lines. The formula is hypoallergenic, free from crystalline silica, cadmium, and lead, and fully biodegradable. Extended working time means three minutes to position and settle before the five-minute set, so there's no rushing.Reviewers rate it for its calm, precise working window. If you already have a Bananakit kit and want a second attempt or a fresh start, this is the straightforward refill.

## Frequently asked questions

## How many molds can I make with one sachet?

Each 453 g sachet contains enough alginate powder to make two complete molds from scratch. If a first attempt goes wrong, you have a second try in the same sachet.

## Is this alginate safe for all skin types?

Yes. The formula is hypoallergenic, non-toxic, and free from crystalline silica, cadmium, and lead. It is derived from natural seaweed and meets dental-grade standards, making it suitable for sensitive skin.

## How long do I have to position before the alginate sets?

You have about three minutes of working time after a 45-second mix. The alginate sets fully in around five minutes. That window is intentionally extended for calm, accurate positioning.

## What water temperature works best for mixing?

Room-temperature water gives the most predictable working and setting times. Warmer water speeds up the set; cooler water slows it down. Start with room temperature until you know the formula.

## Does this work with any casting kit, or only Bananakit?

This is the official Bananakit refill and is formulated to work with their mold kits. It may be compatible with other alginate-based clone kits, but Bananakit's mixing ratios and containers are what the formula is calibrated for.

## How should I store leftover powder between uses?

Seal the sachet tightly and keep it in a cool, dry place away from humidity. Moisture can begin the setting reaction before you are ready, so air-tight storage is important.
