IV. Usage & Storage Tips
The shell is made of soft, thin plastic. Do not fill with hot liquids or sharp objects to avoid puncturing and leaking.
Not recommended for children under 3 years old to prevent accidental ingestion of small filler particles after opening.
Avoid prolonged exposure to direct sunlight, as high temperatures will accelerate plastic aging, yellowing, and loss of elasticity.
Slight mold lines and dimensional errors (±0.2cm) may occur during hand-injection molding, which are within the normal processing range.
After filling, it is recommended to double-seal with a plug and hot melt adhesive to improve leak prevention.
This product only includes a transparent empty shell and a sealing plug; no filler materials are included.
FAQ:
Q1: Do slime, glitter, water or other filling materials come with the item?
A: No fillings are included. We only sell transparent blank plastic shells with matching small lids. All filling supplies like slime, glitter, sequins, beads and liquid need to be prepared by yourself. This is clearly marked on our listing page.
Q2: What age group is this shell suitable for?
A: This DIY craft blank shell is only for users aged 14 and above. It is not recommended for younger people.
Q3: Is the lid sealed? How to add fillers inside?
A: The lids are unsealed and detachable from factory. There is a reserved filling hole. You can separate the lid to pour in all kinds of craft fillers. After filling, you may use glue or hot melt adhesive to seal the hole manually.
Q4: Can I take it apart to change the inner fillers repeatedly?
A: If you do not use strong adhesive for sealing, you can take apart the lid to replace fillers. If the hole is fully glued shut, the shell may break when you try to open it, repeated disassembly is not suggested.
Q5: Is it normal if the shell has tiny scratches or flash edges?
A: This is an injection-molded blank DIY craft shell. Minor mold lines and slight flash edges are normal production traces, not product defects. You can smooth the edges with simple hand polishing.
Q6: What to do if the shell arrives deformed?
A: Slight deformation is caused by high temperature or squeezing during transit. Leave it under normal room temperature for a while and it will recover its shape automatically. Contact our customer for after-sales support if the deformation is severe.
